Which to Choose?
Sublimation patches will have a flat surface that can lend itself to fine details and color arrays. Art with a lot of colors can make a patch bulky or thick when embroidered. However, one reason to choose embroidery over sublimation would be the texture. Embroidered patches have rich texture and dimension because of the threads.
Note, adding a merrowed border to a sublimated patch will help make it look like more of a traditional patch as opposed to a sticker. But sublimated patches smaller than 2.5" cannot have a merrow or satin stitch edge. These patches can only have a laser cut edge.
