I have quilt blocks that are embroidered by my MIL with yellow roses and some blue flowers on them. I really would like to get this top pieced together and quilted. Here is my problem---they were a pre printed kit and the fabric that was used is so thin. Should I just go ahead and quilt them or should I place a piece of white cotton on the back of them then the batting and the backing before quilting? The background of the embroidered blocks are white. Would be interested in any help you can give me. Thanks

Maybe some type of fusible interfacing? I'm sure you'll get lots of ideas.

Why don't you put a block on some batting to see how it looks? If you don't like that, I'd put the white fabric behind it.

I recently backed some old fragile quilt blocks with Pellon fusable interfacing and it made the fragile pieces strong as the rest of the pieces. The interfacing I used was labeled for light to medium weight fabrics. I had never used it before but I will use it again. It made all the difference.

If the fabric is that thin, just layering it with more fabric/batting won't strengthen it. I would use a light weight fusible interfacing to give it more strength.

Fusible interfacing is what I would suggest as well. You want to strengthen the block itself. As Amma said, just layering won't do that.

I agree

I agree also

If you need more agreement - I agree with what amma said too! LOL Get a really lightweight one - it'll not only reinforce the fabric itself but also, the seams.

i find that when i have thin white fabric, i end up using white batting..warm and white. (i usually use warm and natural) of course most battings are white.
can't wait to see what you are going to do with them! can you show a picture of the blocks?!
