I labeled nothing in the beginning, decades ago, but in the last 10 yrs, yes, I label everything I make or sign my name on a label for a group. Say a Project Linus label, I sign my name as the quilt maker. It will help folks down the road, if your quilts end up in thrift stores etc. I know I love seeing quilts that share a bit about the maker, and maybe the reason for the quilt itself. It's your way of saying I existed at some point in time, and that you thought of others.
