Be sure to include some Mylar with your holiday order. This is the most universally popular color – Blue Opal. Just place a mylar sheet on the embroidery surface and stitch over it with a light density fill to let the sparkly mylar shine through! Tear away excess mylar when stitching is complete – looks like metallic thread was used. Suitable for use with Purely Gates and Anita Goodesign mylar designs. MYBO9915.
