Building a Countermarche

Hello everyone!

I am working on building my own countermarche loom with my father back in Pennsylvania when I head home for holidays. I was wondering if someone had a countermarche here in the Austin, TX area. I would like to see one work, maybe even weave a pick or two and take a measurement or two. I would also appreciate anyone  would could help me with loom building tips. I read the other threads and such about the few of you who have built a countermarche and was wondering if you had any tips or things you widh you had done differently.


Thanks in advance for your help! I am very excited to get started.
