Triangles & Stripes Baby Blanket

I had the idea for this baby blanket after coming across a Japanese crochet pattern on Pinterest that had this triangle design. I took that design and turned it into a blanket. My first thought was to do it in a solid color but then I thought it might be fun in stripes. I used three colors and decided to use blues, I thought the geometric pattern in the blanket would work well for a boy blanket but I think it would be cute in girly colors too, and as few or as many colors as you want. 

I decided on a simple single crochet border. I didn't want something really busy that might take away from the blanket design and since I chose to make it a boyish blanket I didn't want anything that would be too frilly.

My blanket ended up about 30x33 inches. A little on the small side but with crocheted baby blankets I feel like kind of small is okay. (Don't mind the teeth marks on the crib, it has been through five kids and has definitely seen better days.) It would be really easy to make it bigger or smaller. 

I will share my written pattern but if you prefer working from a chart you can look here at number 84. You will start by chaining a multiple of 12 plus 6. I started with 90 (7x12=84+6=90). To make it bigger just keep adding 12 until it is as big as you want it. 

Triangles and Stripes Baby Blanket

You will need:

Worsted weight yarn in 3 colors (or as many as you choose to use)
J crochet hook
Yarn needle for weaving in ends

*turning ch 3 counts as a dc

ch 90

Row 1: dc in 4th ch from hook (the first 3 ch create the first dc so now you have 2 dc), [ch 1, sk 1, dc in next ch] repeat until you have one ch left, dc in last ch, ch 4, turn

Row 2: (turning ch 4 creates 1 dc and 1ch) dc in ch 1 space, ch 1, dc in ch space, ch 1, dc in ch space, [dc in dc, dc in ch space, *ch 1, dc in ch space* 5 times] 6 times, dc in next dc, dc in ch space, ch 1, dc in ch space, ch 1, dc in ch space, ch 1, dc in top of ch 3 from previous row, ch 3, turn

Row 3: [dc in ch space, ch 1] twice, [dc in ch space, dc in next 3 dc, dc in ch space, *ch 1, dc in ch space* three times, ch 1] 6 times, dc in ch space, dc in next 3 dc, dc in ch space, ch 1, dc in ch space, ch 1, dc in ch space, dc in top of ch 3, ch 4, turn

Row 4: dc in ch space, ch 1, [dc in ch space, dc in next 5 dc, dc in ch space, *ch 1, dc in ch space* twice, ch 1] 6 times, dc in chain space, dc in next 5 dc, dc in ch space, ch 1, dc in ch space, ch 1, dc in top of ch 3, ch 3, turn

Row 5: dc in ch space, ch 1, [dc in ch space, dc in next 7 dc, dc in ch space, ch 1, dc in ch space, ch 1] six times, dc in ch space, dc in next 7 dc, dc in ch space, ch 1, dc in ch space and top of ch 3, ch 4, turn

Row 6: [dc in ch space, dc in next 9 dc, dc in ch space, ch 1] 7 times, dc in top of ch 3, change colors, ch 3, turn

                       
Row 7: [dc in ch space, ch 1] to the last two stitches, dc in ch space, dc in top of ch 3, ch 3, turn

Row 8: dc in next dc, dc in ch space, [*ch 1, dc in ch space* 5 times, dc in ch space, dc in dc, dc in ch space] 7 times (the last time your last dc will be on top of a ch 3 not in a ch space), ch 3, turn

Row 9: dc in next 2 dc and next ch space, [*ch 1, dc in ch space* 4 times, dc in next 3 dc, dc in ch space] 7 times ending with 4 dc (ch space, dc, dc, top of ch 3), ch 3, turn

Row 10: dc in next 3dc and next ch space, [ch 1, dc in ch space, ch 1, dc in ch space, ch 1, dc in ch space, dc in next 5 dc, dc in ch space] 6 times, ch 1, dc in ch space, ch 1 dc in ch space, ch 1, dc in ch space, dc in next 4 stitches, ch 3, turn

Row 11: dc in next 4 dc and next ch space, [ch 1, dc in ch space, ch 1, dc in ch space, dc in next 7 dc, dc in next ch space] 6 times, ch 1, dc in ch space, ch 1, dc in ch space, dc in next 5 stitches, ch 3, turn

Row 12: dc in next 5 dc and next ch space, [ch 1, dc in ch space, dc in next 9 dc, dc in ch space] 6 times, ch 1, dc in ch space, dc in next 6 stitches, change color, ch 3, turn

Repeat rows 1-12 changing colors every six rows. You will repeat 1-12 four times and then 1-6 one more time, ending with row 6. You should have 9 stripes. Weave in all of your ends.

Border: Join your yarn in any corner, sc around. Sc in each stitch along top and bottom and evenly on the sides, I found that about 2 sc along the side of each dc worked for me, and sc 3 times in each corner. Join with a slip stitch to your starting sc, ch 1, sc around again working 3 sc in each corner. Finish off and weave in ends, you may need to do some blocking to make it look squared. Mine was a little trapezoid shaped when I first finished.

That is it, if you try this pattern and have any problems please let me know. It is really a pretty easy pattern once you start going but I had a hard time figuring out how to write it down. Once you start getting the pattern going it really makes sense where the chain spaces are and where you double crochet but this pattern has more to it than any other pattern I have ever tried to write down so I hope it makes sense. Please, let me know if something seems wrong or confusing and I will try to help.
