Hello craft world! I am in the process of starting a fabric wall decal business... nothing major just something fun for my sister and I to do... I have made some super cool decals in my own home, but here lies the problem... I have been using repositionable spray adhesive, letting it tack up for a few minutes then applying it to my wall... I am looking for some form of glue that i can back with wax paper, ship, and when the buyer peels off the wax paper it is sticky enough to stay on their wall until they wish to remove it!  Think, contact paper.  any ideas?  thanks so much!  -Erin
