I have no problem with tied quilts......I think you would probably need to tie in pretty much every hexi and if they are small thats going to be a lot of ties. If you don't want them to show as much use thread colors that match each place that you tie and/or tie so the knot is on the back of the quilt. When I tie a quilt I use a high loft poly batting I just like how it looks.
So will someone tell me what you consider to be the difference between a quilt and a comforter?
