Last summer I had been thinking of making some coasters when I happened to watch the episode of Knitty Gritty which featured the pattern for these.
Pattern:
It's so Mod: Coasters by Iris Schreier.
Yarn:
Lily Sugar'n Cream in Summer Splash.
Needles:
US size 7 (4.5 mm) circular (Denise).
Hook:
US size G (4.25 mm) aluminum (Boye). Used for a crochet cast-on.
Modifications:
Since the cast-on forms the entire outside edge of the coaster, I decided to go with a crochet cast-on for a nice, neat look. Once all the triangles are complete, the pattern calls for a 3-needle bind-off to attach the last triangle to the first. I thought this made too obvious of a seam so I grafted them together in garter stitch instead. As a finishing touch, I took the beginning yarn tail, untied the initial slip knot, and sewed a couple extra chains in place to connect the beginning of the crochet cast-on with the end.
Notes:
I love how the modular wedges and the garter stitch work with variegated yarn in this pattern. My only reservation is that, at least in my case, the first triangle always turned out a little bit bigger than the rest so my coasters are slightly lopsided.
