I'm a new weaver using a Baby Wolf and finding it frustrating to get my warp on the loom evenly. I think I have it tied on evenly to the back and front beams and wound with an even tension but once I start weaving I run into problems with the outer threads getting tighter than the inside threads creating a scalloped look on the cloth. I've noticed that the thread on the back beam pulls tighter at the outer edges and not on the inside creating a mound in the middle and not on the ends. I've also started using a stretcher bar which helps the selvedge from pulling in but I'm still not happy about irregular look I get when I beat the cloth (is that the right term ?? :) ) and end up cutting it off and starting again which is a waste of materials. I am using paper to wind the back beam. Any hints you can give me would be welcome!
