Because I use a lot of fabric, I seem to hoard a lot of fabric, I have a lot of selvages. A few years ago I started saving them (instead of... GASP! throwing them away). They filled my giant jar slowly and steadily. Then they ended up all over my basement as the kids got their hands in the jars. Recently I cleaned up my jars - strings were donated for charity quilts, snippets got sewn together a bit, and the selvages were sent away.
You see, I may keep the selvages. I may admire the selvage quilts you find, but I have no real interest in making one. I've got enough want-to-dos on my list that a selvage quilt will never find its way to the top of the list. So I packed them up and sent them off to quilty friends who would make very good use of them.
It is easy to get caught up in making every single cool idea you see. So easy to think you need to keep everything for one day. I just saved my stuff for someone else's one day.
And now my jar is empty, all ready to be filled as I play with fabric again.
