If some of them are small, maybe make a wall hanging or two~~

How about making throw pillows?

You don't have to keep them exactly as they are. You could change the shape or size, either cutting to fit or with templates or patterns. For example, you could use them as part of either a Drunkard's Path or a Dresden Plate.

My thoughts exactly. Or you could put them on the back of quilts in ones or groups. If they don't blend maybe cushions with plain back.

I have put then in picture frames and use then as Art for my sewing cave.

Or, you could cut them up....disappearing nine patch style,mix them up a little...put with neutral sashing.

I like the idea of tote bags. But then use them for "gift" wrapping at Christmas time. You get to use them, save paper, and each will hold a treasured memory.

totes everyone loves them, especially your favorite charity.

This is what I usually do with mine. Or you could make table toppers or mug rugs.

Purses or tote bags would use some of them up. Either one on the front or one on the front and a complimentary one on the back. Use them for gifts if you have a bunch and don't need a bunch of purses or tote bags. Oops, others have beat me to the punch.
