Here you find the free crochet pattern for my Spectrum corner-to-corner crochet blanket with an ombre colorway.  Due to the double strand this project works up fast and the final result is a very warm blanket. This project is perfect for stash busting if you have half-balls of yarn left from other projects.

Final Measurements

The final size of your blanket will depend on your gauge and personal style of crochet. If you follow my gauge and blocking your blanket will be approximately 135cm x 155cm when finished. This is a comfortable lapghan for use in a comfy couch.

Abbreviations

Please note that US Crochet Terminology is used for this pattern. If you are more familiar with UK terms, please use this conversion chart as needed.

• ss – slip stitch
• s – stitch
• ch – chain
• dc – double crochet
• RS – right side
• WS – wrong side
• pixel – ch3 and 3dc worked into a ch3-space

Notes

The entire blanket is worked using two strands of yarn at the same time. Sometimes you work with two strands that have the same color, sometimes two strands with a different color. Keep paying attention to changing color at the appropriate points. When changing color you will always change only one of the two strands.

Tip: split each ball of yarn into two equal cakes to make it more easy to use two identical strands at the same time.

This blanket is made using corner-to-corner technique. I have a video tutorial available that is part of my Crochet Fundamentals series to show you the general steps involved in C2C.

Gauge

As such, gauge is not critical for this project. If you want to obtain a blanket similar in size to mine your blanket should to be about 14cm x 14cm after row 6 (unblocked). Change your hook size appropriately if needed.

Spectrum C2C Blanket – Free Crochet Pattern

Work the blanket in 4 distinct stages; first start with increasing the diagonal of the blanket, secondly keep the diagonal constant and increase only the length of the blanket, thirdly decrease the diagonal of the blanket to finish the inner part, and lastly make the border.

Increasing the diagonal

In the first part of the pattern increase the diagonal till the width of the main part of the blanket is reached.

Row 1 (RS) Use two strands of Color A. Ch6 (counts as ch3 and 1dc), 1dc in fourth ch from the hook and in each of the next 2 ch to the end. Turn your work. [1 pixel]

Row 2 (WS) Ch6 (counts as ch3 and 1dc), 1dc in fourth ch from the hook and in each of the next 2 ch to complete a pixel. With the WS of pixel 1 facing and the RS of the pixel of Row 2 just worked facing, line up the top of the dc just worked with the top of the dc’s of from Row 1 so that the 2 pixels are touching. ss in the space created by the ch3 at the top of pixel of Row 1, ch3, 3dc in ch3-space. Turn your work. [2 pixels]

Row 3 (RS) Ch6 (counts as ch3 and 1dc), 1dc in fourth ch from the hook and in each of the next 2 ch to complete a pixel. Rotate the pixel just worked so that you can ss in the ch3-space at the top of the last block worked from Row 2. ch3, 3dc in same ch3-space as the ss. ss in ch3-space at the top of the next pixel, ch3, 3dc in the same ch3-space as the ss. Turn your work. [3 pixels]

Row 4 Ch6 (counts as ch3 and 1dc), 1dc in fourth ch from the hook and in each of the next 2 ch to complete a pixel. Rotate the pixel just worked so that you can ss in the ch3-space at the top of the last block worked from the previous row. * ch3, 3dc in same ch3-space as the ss. ss in ch3-space at the top of the next pixel. * Repeat from * to * until you have worked a ss in the ch3-space of the last block of the previous row. ch3, 3dc in the same ch3-space as the ss. Turn your work. [1 pixels more than the previous row]

Rows 5 – 47 Repeat Row 4 using the following colors for each row:

• row 1 – 4: 2 strands of Color A (already worked, but given to be complete)
• row 5 & 6: 1 strand of Color A & 1 strand of Color B
• row 7 – 10: 2 strands of Color B
• row 11 & 12: 1 strand of Color B & 1 strand of Color C
• row 13 – 16: 2 strands of Color C
• row 17 & 18: 1 strand of Color C & 1 strand of Color D
• row 19 – 22: 2 strands of Color D
• row 23 & 24: 1 strand of Color D & 1 strand of Color E
• row 25 – 28: 2 strands of Color E
• row 29 & 30: 1 strand of Color E & 1 strand of Color F
• row 31 – 34: 2 strands of Color F
• row 35 & 36: 1 strand of Color F & 1 strand of Color G
• row 37 – 40: 2 strands of Color G
• row 41 & 42: 1 strand of Color G & 1 strand of Color H
• row 43 – 46: 2 strands of Color H
• row 47: 1 strand of Color H & 1 strand of Color I

Constant diagonal

In this part the diagonal is kept constant. This means that the number of pixels per row is the same for each row. At this point you should have 47 pixels on your diagonal.

Row 48 Turn your work. Using 1 strand of Color H & 1 strand of Color I ss into the next stitches and into the ch3-space. * ch3, 3dc in same ch3-space as the ss. ss in ch3-space at the top of the next pixel. * Repeat from * to * until you have worked a ss in the ch3-space of the last block of the previous row. ch3, 3dc in the same ch3-space as the ss. Turn your work. [47 pixels]

Row 49 Using 2 strands of Color I, ch6 (counts as ch3 and 1dc), 1dc in fourth ch from the hook and in each of the next 2 ch to complete a pixel. Rotate the pixel just worked so that you can ss in the ch3-space at the top of the last block worked from the previous row. * ch3, 3dc in same ch3-space as the ss. ss in ch3-space at the top of the next pixel. * Repeat from * to * until you have worked a ss in the ch3-space of the last block of the previous row. Do not work a pixel on top of the last pixel from the previous row. [47 pixels]

Rows 50 – 59 Repeat Rows 48 and 49 using the following colors for each row:

• row 48: 1 strand of Color H & 1 strand of Color I (already worked, but given to be complete)
• row 49 – 52: 2 strands of Color I (already worked, but given to be complete)
• row 53 & 54: 1 strand of Color I & 1 strand of Color J
• row 55 – 58: 2 strands of Color J
• row 59: 1 strand of Color C & J strand of Color K

Decreasing the diagonal

In this part of the pattern the diagonal is decreased to form a rectangle.

Row 60 Turn your work. Using 1 strand of Color J & 1 strand of Color K ss into the next stitches and into the ch3-space. * ch3, 3dc in same ch3-space as the ss. ss in ch3-space at the top of the next pixel. * Repeat from * to * until you have worked a ss in the ch3-space of the last block of the previous row. Turn your work without working on top of the last pixel. [1 pixels less than the previous row]

Rows 61 – 105 Repeat Row 60 using the following colors for each row:

• row 60: 1 strand of Color J & 1 strand of Color K (already worked, but given to be complete)
• row 61 – 64: 2 strands of Color K
• row 65 & 66: 1 strand of Color K & 1 strand of Color L
• row 67 – 70: 2 strands of Color L
• row 71 & 72: 1 strand of Color L & J strand of Color M
• row 73 – 76: 2 strands of Color M
• row 77 & 78: 1 strand of Color M & J strand of Color N
• row 79 – 82: 2 strands of Color N
• row 83 & 84: 1 strand of Color N & J strand of Color O
• row 85 – 88: 2 strands of Color O
• row 89 & 90: 1 strand of Color O & J strand of Color P
• row 91 – 94: 2 strands of Color P
• row 95 & 96: 1 strand of Color P & J strand of Color Q
• row 97 – 100: 2 strands of Color Q
• row 101 & 102: 1 strand of Color Q & J strand of Color R
• row 103 – 105: 2 strands of Color R

Cut off your yarn and bind off.

Yarn tails & blocking

Before continuing with the border it is wise to work away all your yarn tails from the center of the blanket. I also suggest blocking your center before doing the border. The C2C stitches tend to pull inward and your border will be very wobbly if you don’t block the blanket first.

The unblocked inner part of your blanket will be about 110cm x 130cm. Block this to 125cm x 145cm. Your blocked blanket will look something like this.

Border

Row 1 *(sc, ch2, sc) in the corner of any pixel at the corner of the blanket. ** ch3, skip the next pixel, sc between two pixels. ** Repeat from ** to ** till the last pixel, ch3, skip to the corner pixel. * Repeat from * to * 3 more times. Close with a ss to the first s. ss to corner ch2-space.

Row 2 (ch3, dc, ch2, 2dc) in ch2-space. *skip next sc, 3dc in next ch3-space * Repeat from * to * till the last ch3-space, skip last sc. *(2dc, ch2, 2dc) in ch2-space. ** skip next sc, 3dc in next ch3-space. ** Repeat from ** to ** till the last ch3-space, skip last sc. * Repeat from * to * 2 more times. Close to ch3 with ss. ss to ch2-space.

Row 3 (ch3, dc, ch2, 2dc) in ch2-space. 1dc in every s till the end. *(2dc, ch2, 2dc) in ch2-space. 1dc in every s till the end. * Repeat from * to * 2 more times. Close to ch3 with ss. ss to ch2-space.

Row 4 – 6 Repeat row 3. Close row 6 with an invisible join.

Block again to Finish

Weave in all ends and block one more time to approximately 135cm x 155cm. Especially the border will need blocking because it will wobble a bit after completing.

And then you are all done!
