Four Square Single Crochet Baby Blanket

Your First Colorwork Baby Blanket

Choose four favorite colors and create the four square single crochet baby blanket! This is the perfect baby blanket for you to try your hand at colorwork for the first time!

You also avoid seaming!!

In crochet colorwork, you often have several skeins or bobbins of yarn attached at a time to create intricate designs. If you’ve never tried your hand at colorwork, this is an easy introduction as you’ll only have two skeins of yarn attached at a time.

This pattern is suitable for beginners who have worked up any project in single crochet before! I have a VERY detailed photo tutorial below.

I hope you enjoy this pattern!

This blanket is part of a series I made for twins! See the companion pattern here: Single Crochet Back Loop Only Baby Blanket

I had quite a bit of yarn left over for this blanket! You should easily be able to size up to say 36″ x 36″ if you’d like. Conversely, if your gauge matches mine, you could size down to 30″ x 30″ and SHOULD only need one skein of each color yarn. Last, it would be very easy to substitute and buy one larger skein of each color from a brand like Red Heart or I Love This Yarn. Good luck and enjoy!

For the cleanest start to this blanket, it makes the most sense to start with a foundation single crochet rather than a long chain. If you have never done fsc before, I recommend this video from Moogly: Foundation Single Crochet (FSC).

A few FSC tips:

Practice for a little bit before starting your blanket. I found I had some tension issues when I first attempted foundation single crochet, but with practice, especially keeping a looser tension, I was able to start off my blanket well.
As with an ordinary chain beginning, the chain stitch portion of the foundation single crochet stitches should be worked more loosely so the row does not curve. This is in part where practicing comes in. Pull the loop of the chain stitches up just a tad to help loosen the tension.

Turning ch never counts as a st.

To adjust the width of the blanket, fsc any even number, changing colors halfway.

Cut yarn, fasten off, and weave in ends.

I’d also suggest blocking this blanket for a more polished, perfect square! Here is a great video from TL Yarn Crafts on blocking acrylic yarn with steam: How to Steam Block Acrylic Knit & Crochet Projects

Four Square Single Crochet Baby Blanket Photo Tutorial

Row 1: Using color A, fsc 48, switch to color B, fsc 48, ch 1, turn. <96 sts here and throughout.>

1. To foundation single crochet (fsc), hold your work vertically. Ch 2.

2. Insert your hook in the second ch from hook.

3. Yo and pull up a loop loosely. You will have 2 loops on your hook.

4. Ch 1. You will still have 2 loops on your hook.

5. Yo and pull through both loops on your hook. This is your first foundation single crochet stitch!

6. Working underneath the fsc you just created, insert your hook under two loops.

7. Yo and pull up a loop loosely.

8. Ch 1.

9. Yo and pull through both loops on your hook. This is your second fsc.

10. Continue making fsc stitches. Insert your hook under two loops beneath the fsc you’d just created.

11. Yo and pull up a loop loosely.

12. Ch 1.

13. When you are ready to change color, lay the new yarn color over your hook as you are about to finish the last stitch in your first color.

14. Pull through.

15. Insert your hook under two loops beneath the fsc you’d just created.

16. Yo and pull up a loop loosely.

17. Ch 1.

18. Yo and pull through both loops on your hook.

19. Insert your hook under both loops beneath the fsc you’d just created.

20. Yo and pull up a loop loosely.

21. Ch 1.

22. Yo and pull through both loops on your hook.

23. Continue making fscs until you have the same number of colors A and B. In this small swatch, I’ve done 5 fscs in each color, 10 total.

24. Ch 1 and turn. We will hold our work horizontally moving forward.

Row 2: Sc in the next 48 sts, as you complete the 48th sc pick up color A, sc in the next 48 sts, ch 1, turn.

25. To sc, insert your hook in the first st (the last fsc of Row 1). Yo and pull up a loop.

26. Yo and pull through both loops on your hook.

27. Sc in each st across. When you are working the last st in the current color, stop when you have 2 loops on your hook.

28. Loop the next color over your hook. It will be right there waiting for you. :)

29. Pull the new color through both loops on your hook.

30. Sc with the new color in each st across.

31. Ch 1 and turn.

Row 3: Sc in the next 48 sts, as you complete the 48th sc pick up color B, sc in the next 48 sts, ch 1, turn.

32. Just like in the previous row, when you are about to complete your last stitch in the current color, stop when there are two loops left on your hook.

33. Loop the next color over your hook, which should be there waiting for you.

34. Pull the new color through both loops on your hook.

35. Continue working scs in each st across.

36. Optional: for an extra straight edge, you can work your last sc of each row into the front loop only and horizontal bar of the last st. This is a tip I learned from the book Crochet Secrets From The Knotty Boss! Here is what that looks like.

Insert your hook up through the front loop only of the next single crochet, then down through the horizontal bar portion of the stitch.

37. You should see an X when you insert your hook into these parts of the stitch.

38. Complete your single crochet as you normally would. Look at that nice, straight edge!

39. NOTE that this gorgeous straight edge only shows on one side of the blanket at a time, though. The other side will still have bumps:

Rows 4-64: Rep Rows 2-3. You’ll end on Row 2 of the repeat.

Row 65: Join color C, sc in the next 48 sts, as you complete the 48th sc join color D, sc in the next 48 sts, ch 1, turn.

40. To join a new color at the end of a row, I like to simply loop the new color over my hook.

41. Pull the new color through the loop on your hook.

42. Pull on the tail of the old color to tighten.

43. Ch 1. This is your ch 1 before turning.

44. Pull on the tail of your new color to tighten. Beautiful!

45. Sc in each st across. When you are working into the last st above the first block of color, stop when you have 2 loops on your hook.

46. Pull up the loop of the old color B and put it on your hook. ALSO, loop the new color D on your hook.

47. Pull both strands (the old color B and the new color D) through the two loops on your hook.

48. Pull on any yarn tails to tighten your stitches.

49. As you begin your sc in the next st, insert your hook and pull up a loop of only the new color D.

50. Yo and pull through all the loops on your hook.

51. Sc in each st across, remembering to work under the front loop and horizontal bar of the last st if you’d like that super straight edge!

Row 66: Sc in the next 48 sts, as you complete the 48th sc pick up color C, sc in the next 48 sts, ch 1, turn.

52. When you reach the last st in color D for this row, you’ll work under all the loops of that extra thick stitch.

53. Insert your hook beneath the strands of color D and B here and pull up a loop.

54. Yo with color C and pull through.

55. When you get to the last st of this row, it will be tricky trying to work into the front loop and horizontal bar because of the way we’d joined the new color previously.
