I have been given some Sunbonnet Sue blocks in Thirties prints (I think they are original, not reproductions). Some have been appliqued onto stained muslin with black floss in a buttonhole stitch. Some have just been basted together, ready to applique. 25 in all. I want to replace the muslin with new muslin. Debating on whether to use black floss to redo them, and match the colours in the pieces with darker shade. I have a ton of floss from a store closing. I don't have a pictures at this time.

Isn't black stitching traditional for Sue blocks?

I would certainly replace the stained muslin. You don't have to use black floss if you would like to match colors instead.

If the blocks are for you, I think you should do what pleases you. Different colored floss could look really cool

When I was 12 years old, my aunt taught me how to applique Sunbonnet Sue blocks. We used black embroidery floss. I still have those little blocks -- notice I said "blocks" and not quilt!!?? Those little jewels were cut from double knit polyester and stitched onto white cotton squares!!! Imagine that!!! ;-)

I agree, use whatever colored thread you want on them :D:D:D

The black is traditional, but I think it would look nice to match the floss with the predominant color of each block!

I think you shoulddo it the way you want, since you are the one who gets to see it every day! Hope you will post a picture when you finish!

It will be a fusion quilt, a little old and a little new. Do it the way it pleases you. Totally agree on changing the background.

You might be able to get the stains out of the muslin by soaking the blocks in some Oxi-Clean & water.
