OK I went upstairs and got the pattern
Its a photo copy and I don't remember the name of the book I got it from (returned it to the library months ago)
But here is what it says:
approx. 38" square
approx 388 yards of blue, yellow, red, green
approx. 291 yards of white
Notes: Work with 2 strands of yard held tog throughout (but doesn't specify the same color so hence my confusion). The afghan is made in 4 squares then sewn tog for one large square. There are 110 rows (11 stripes) in each square.
Worked in garter st. work 10 rows of each color.
With 2 strands cast on 117 sts. K 1 row
next row k57, k3tog, k 57 -115 sts k 1 row
next row k56, k3tog, k 56 - 113 sts k1row
cont in this way to dec 2 sts at center every other row until 13 sts rem. Cont to dec. 2 sts at center of every row until 1 st rem.
There are 110 rows in total. Fasten off. make 4 total.
