Coasters are a way to use up left-over yarn in your stash. Make up several sets to keep on hand in your "gift closet". The 100 % cotton yarns soak up moisture and garter stitch pattern makes a firm, but cushiony "base" for coaster.. I made a set in wool yarn to felt. I changed the pattern from garter stitch to stockinett pattern, realizing garter stitch pattern would not show up after "felting". I used a multi-colored yarn, self-stripping, I think---loved it! BASIC SKILLS NECESSARY Basic knitting and some experience with "short row" technique.---just follow the directions and all will be well! GAUGE 4sts = 1 inch; accurate gauge is not essential SIZING / FINISHED MEASUREMENTS Coasters measure about 4" across COLORWAY solid colors show up pattern best!
