I bought the cotton Bucle Kit Granny Pam. I have left over Bucle and I'd Like to buy the same color cotton but in regular 8/2 instead of Bucle. My thought was to make more towels using regular 8/2 for the warp and the bucle for weft. I think i need to modify the EPI. When I used Bucle for warp I used 12 EPI but If I use the regular 8/2 cotton should I change it to 18 EPI? or something else?
