I decoded the pattern - it looks like the real afghan is in white cotton. I used worsted acrylic. Mine is fuzzier, but I think I got the pattern right.
And the pattern that I figured out:
Cast on 15
Knit 6 rows (garter st) before beginning pattern.
R1: K4, (YO, K1) 7 times, YO, K4
R2: K4, P15 , K4
R3: K4, K2tog, K11, SSK, K4
R4: K4, K2tog, K9, SSK, K4
R5: K4, P2tog-tbl, P7, P2tog, K4
R6: K4, K2tog, K5, SSK, K4
Repeat for length desired.
Knit 6 rows garter st. BO.
Combine strips to make afghan of width desired.
My swatch was Size 6 needle and regular weight yarn.
It looks like the strips were joined with a crochet join. Edging is a garter stitch sawtooth with a couple of YO holes in it.
