There are many companies that sell designs for quilt blocks and many more that sell software programs to do it. I just went to a DIME show yesterday, that have lots of stuff to do embroidery on quilts. I'd really check them out. I was impressed with what they have and I've been embroidering for a long time. The main thing about embroidering on a quilt is to have a large throat space. like in quilting, it still makes it easier to do it with a big space to hold the quilt.
