The Ripple Mania Crochet-A-Long ran from 10/17/2012 to 11/28/2012 and was graciously sponsored by Leisure Arts, Lion Brand Yarn, Magique Enterprises, and Red Heart. Each week, a new lesson was posted along with ripple stitch patterns. I've compiled the weekly lessons from the CAL and the patterns into 2 PDFs. The 16 page Weekly Lessons PDF will teach you everything you need to design your own fabulous ripple projects - how to select a color palette, how to increase and decrease, how to design your own ripple stitch patterns, how to "square up" your ripples if you want to have straight (modular) pieces, and how to combine ripple stitches with hexagon and square motifs. If you just want to dive into the patterns, that's ok, too. There's a 17 page pattern PDF with US pattern abbreviations that includes 7 stitch patterns and 3 project patterns. Project patterns: Ripple Square Baby Blanket: Finished size: 30" x 30" (76 cm x 76 cm) or 40" x 40" (101.5 cm x 101.5 cm) Materials: Medium/aran weight yarn in two to four colors (61-73 yds/55.75-66.75 m of main color for each square, 22-26 yds/20-23.75 m of edging color for each square). Small size blanket uses 9 squares; larger size blanket uses 12 squares. US J-10/UK 4/6 mm crochet hook or any size needed to obtain gauge Yarn needle Gauge/Tension: 1 square including edging = 10" (25 cm). Exact gauge is not critical for project.
