I am of the old school, still use old fashioned quilting tools. My "rulers" are wooden yardsticks - I have a 1 ft, 2 ft, 3 ft. and 4 ft.
I think some of the new tools are kind of silly, that you see in catalogs. Do I really need to spend $16. for a little container to hold my snipped off thread ends? I thought that's what the floor was for. ;-)
