Several weeks ago I shared my monogrammed sweatshirt, and while I had lofty intentions of monogramming all my blank shirts, it hasn't happened... YET. But I did manage to monogram a sweatshirt for Amy, and decided to put Jolson's Interlocking Floss Stitch Monogram to use.
A quick word of caution, the way this is digitized there are several jumps within each letter. I'm not exactly sure why, IMHO they could have been minimized. So if you are like me and don't have a machine that trims every jump within a color, keep an eye on it as it stitches. This won't keep me from using it again though, I really like the hand stitched look!
