A couple of quilters were tossing their scraps - and some other quilters were saying/asking - could they have them?

If you are among those that can/will use scraps - what is the smallest size scrap that is usable?

I saw some miniature quilts at Paducah - and they had pieces that looked like they were about 1/2 inch square (before sewing) -

I saw someone say they could use scraps as narrow as 1/2 inch???

Just wondering -

The suggestion to toss scraps into a priority mail box is a good one - just wondering about the size of scraps - I would be less than thrilled to get a bunch of snippets
