I have a question regarding substituting a yarn in a pattern. I am looking at the free Weaving Today projects for beginners page 6 Elegant Placemats. The pattern calls for 3/2 pearl cotton but all I have is 10/2 pearl cotton. I am assuming I would have to recalculate to increase my width and I think my epi would go from 12 to 24 is this correct? Is there anything else I should be considering? Or is this something I should not consider doing at all? I am working on a 4 shaft Dorothy 6 treadle loom with a 12 dent reed.
Thank you in advance, Hollyann
