Can someone direct me to any tutorials that teach how to use jpeg to create a rhinestone template? I purchased Sure Cuts A Lot 2 but can't figure it out.This is similar to what I would like to make except with these all combined together for a t shirt design and car decal.What I'd like to do is use Superheroes but without the shadowing and with the tail and in the tail T ball then under that Mom with the "o" replaced with a baseball filled with clear stones and the laces in red and the M's filled with clear and ourlined in the red stones - then want to have option to have Gran and Grandma to replace the MoM. And use the design for both a t-shirt and car decal then use it to create a vinyl cut out for the batting helmets, of course without the MoM. I'd appreciate any advise. Thanks, BB
