I'm a newbie especially to my 20" flip (which I love!)... I want to make tea towels with a family tartan pattern using plain weave... I want more than one repeat of the pattern, so, from the little I know about weaving, I'm thinking with 200 slots/eyes, isn't enough and i'll have to use thin yarn? Is a tartan tea towel even possible on a 20" flip? Is this something I would have to use two heddles for? I'd like to take a class for this (Washington/oregon)... any advice and/or suggestions would be appreciated... thanks!
