OK, so I have measurements for the wooden bed frames a friend made for his granddaughters and their dolls…and I have in my notes that one likes purple and green, and the other likes pink and yellow. This is totally do-able, no? (BTW, I love this yarn for this project!)

Cast on 66…should be 14” wide, work to length of ≈19”.
Finished size 21”x16”. These turned out better than I expected! Yay!

F hook for Crochet edging…use white.
1 sc in each stitch on top and bottom; 2 sts. for every 3 rows on sides; 5 sts in corners.
hdc, ch 1 around, (hdc, ch 1) x2 in corners.
sc, ch 3 around, (sc, ch 3) x2 in corners.
sc, ch 1 around (sc, ch 1) x2 in corners.

I added two rows of colored yarn (same as blanket colors) around the white to tie the border into the blanket.
Round 1: sc, ch 1 around.
Round 2: (sc, ch1, sl st, ch 1) repeat around.
