I'm an intermediate knittter who just moved into an area with no knitting shop and no known knitting community. Help! I'm trying some simple patterns, but still have really basic questions. Here's my latest question:
I am trying a simple poncho--basically a very wide scarf/shawl knitted in a rib that you sew together at one end (in Reader's Digest Two Stich Knits). It calls for Rowan Kid Classic (mohair mix?) and size 8 needles. I couldn't find anything like that in Hattiesburg, MS (go figger!), so I picked up a Patons Shetland chunky Tweeds that calls for size 10 needles. I thought I would slightly adjust the pattern (decrease cast on), but that didn't do it. It seems like it's going to be way too large.
Is there a general rule of thumb for making these adjustments? Is it OK to get a different kind of yarn than what the pattern calls for? When you do that, do you go with the original pattern needle size or use the needle suggested for the yarn?
Thanks so much for your help!
