Figuring out pattern
I am a new beginner at knitting and I found this afghan pattern in a beginner book but the pattern will not come out correctly. Can anyone tell me how many stitches I need to cast on and how many stitches I need to increase evenly for the pattern. Here is the instructions.
Cast on 188 stitches.
Row 1-7 Knit across
Row 8 Knit across increasing 30 sts evenly spaced.
Row 9 (right side) K4, *P2,K2,P2, (K4,P2)twice, K2,P2, K4; repeat from * across.
Row 10 K6, P2, K2, (P4,K2) twice, P2, * K8, P2, K2, (P4,K2) twice, P2; repeat from * across to last 6 sts K6.
Row 11 K4, * P2, work twist, P2, (K4,P2) twice, work twist, P2, K4; reat from * across.
Row 12 same as row 10.
Row 13 K4, * P2, work Twist, P2, work front cable, P2, work back cable, P2, work twist,P2, K4, repeat from * across
I figured out that row 9, 11, 13 had 30 stitches and row 10, 12, had 56 stitches. The pattern has 26 stitches. If I wanted to make this afghan 48 " x 68" how many stitches do I need to cast on and how many stitches do I need to increase evenly. Its not coming out as written.
Thanks for any help given.
