I copy patterns I like from magazines and then donate the magazines to the donation table at the guild. I have a copier/printer.
Copied patterns are divided into applique, pieced, and foundation piecing in 3" ring binders. I then divide them alphabetically by type, ie. holiday, children, flowers etc. with sheet dividers. If a category starts being to big I'll divide it. Since I like irises I have a separate binder for those no matter if they are applique or pieced.
I am chairman for our charity quilts for the guild and easy and quick patterns are in a master file in sheet protectors in a 3" ring binder. I will print 2 or 3 copies that the ladies can take home and make a quilt. (There are many free quick and easy patterns on line.)
