Triangle baby blanket - Pattern

Here's the pattern for the triangle blanket that has gotten so much positive response. I hope the pattern is easy to read and that making it will bring you as much joy as it brought me c",)

Triangle:
Ch 5, join together with a slip st.
Rnd 1: Ch 3 (counts as 1st dc), 2 dc in the ring, ch 4, 3 dc, ch 4, 3 dc, ch 4, join together with slip st to top of ch-3.
Rnd 2: Ch 3 (counts as 1st dc), dc in next 2 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 3 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 3 dc, *3 dc, ch 4, 3 dc* in ch-4 space, join together with slip st to top of ch-3.
Rnd 3: Ch 3 (counts as 1st dc), dc in next 5 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 9 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 9 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 3 dc, join together with slip st to top of ch-3.
Rnd 4: Ch 3 (counts as 1st dc), dc in next 8 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 15 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 15 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 6 dc, join together with slip st to top of ch-3.
Rnd 5: Ch 3 (counts as 1st dc), dc in next 11 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 21 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 21 dc, *3 dc, ch 4, 3 dc* in ch-4 space, dc in next 9 dc,join together with slip st to top of ch-3.
Triangle is ready.

Make 54 triangles, or 18 of each color if you have 3 colors.

Arrange the triangles in the order you want them before you start joining them together.
1. row: 7 triangles
2. row: 9 triangles
3. row: 11 triangles
4. row: 11 triangles
5. row: 9 triangles
6. row: 7 triangles

Joining:
The triangles are joined together with sc. Put the triangles together, backsides facing each other, 1 sc in each ch. The sc tend to lean in one direction so be careful always to crochet in the same direction so all the sc lean in the same direction.


Edging:
Rnd 1: Start in what ever chain you want to, ch 1, 1 sc in the same st, 1 sc in each st. Make 5 to 7 sc in the corners (what ever you think fits best). Join with slip st in the 1st sc of the round.
Rnd 2: Ch 1, 1 sc in same chain, 4 sc, 1 picot, *5 sc, 1 picot*, repeat from * to * till the end of the round. Join with slip st in the 1st sc of the rnd.
