As promised, here is the pattern for the afghan. It's pretty easy if you know how to crochet. If you don't, and you want to learn how, there's TONS of good videos on You Tube, so go buy some yarn and a hook, and get goin'! Then come back, and use this pattern to make an afghan!
Row 1: ch 122
Row 2: hdc in 3rd st from hook, hdc in every st to end of the row.
Row 3: ch. 1, sc in first st., skip 2 st's, then make 5 dc's in next st, skip 2 st's, sc in next st, repeat until end of the row
Row 4: ch. 3, then do 2 dc in first st. skip 2 st's, 5 dc's in next st, skip 2 st's, sc in next st, skip 2 st's, repeat until last st, then do 3 dc's in last st.
Repeat rows 3 and 4 until it's as long as you want it.
Once it's as long as you want it, finish it off with a row of hdc in each st.
Then, add the scalloped trimming, and you're done!
