Many years ago , before I thought I would ever have an embroidery machine, I purchased some embroidered squares with care bears on them from eBay..... I have found them after rummaging for something else, and I would like to put them into a quilt for my GD, who is collecting care bears, now, my question is that it appears that they have been embroidered on a poly cotton material and I want to put 100% cotton material that co-ordinates the blocks would you suggest that I use interfacing on the embroidered blocks to give them support against the cotton, or should I use them for something else, I have 12 of them ?? Ideas and suggestions most welcome. Thanks heaps Trish.
