They might have been a sample pack from a mail order company. What's wrong with stitching 5/8" finished anyway?

Say's she who is getting into miniature piecing...

Iron them on a backing fabric using steam-a-seam 2, make a "watercolor" wall hanigng

Says you! :D They sound just about perfect for me, but then I love miniatures.

A few years ago Eleanor Burns did a show on using small fabric squares by fusing them onto a fusible grid then she accordion-folded vertically and sewn the 1/4" seam allowance, then repeated horizontally. I would suggest checking her site for more information. Her finished project was perfectly assembled and thought this is a method on my "to try" list.

I sewed about half the 250 of mine, that were samples from a fabric company, into rows and the rows into a doll quilt for a great grandDaughter and she uses it for her 'babies' and her my little pony. The remainder (solid color) I folded into prairie points and onto a strip of paper piecing tissue that will probably be used as hem trim on a denim 18" doll skirt.

How about stitching them together for a funky boarder on a scrap quilt?

I would use that grid-ed fusable stabilizer to make way too. Or dog beds. I wouldn't want to try and piece them.

art quilt. place, drop, fling them onto a dark background . add pieces of strings , braids, ribbons,whatever . cover with white tulle and stitch any way you want to make an interesting abstract art quilt.

Maybe toss in a jar and use for room decor? (grin)

You are a brave woman. I made a quilt with 1" finished squares but 1" unfinished - wooo!
