The border on the blocks are scraps left over from making my Triangle Tiles quilt. The center is muslin. I have a collection of old and new iron on embroidery transfers that I've been using for the centers. I've been using two strands of floss for the embroidery. I like to use variegated threads.
When I use up the rest of the scraps I'll probably make a different size of block to use up other thirties reproduction scraps.
