I'm sorry but I hate spray glue stuff. No matter how much I use, it gums up my needle. So I just use straight pins to stick things together. Been doing it for several years. Being careful not to get a pin in the sewing field. And removing them as I go. Just works best for me.
If you happen to use rayon instead of poly, be sure & do not bleach! We have a very strange colored frog on one of my grandkid's towels!
I use sulky sticky stablizer and poly thread and I never have a problem. Can't wait to see the finished project!
I often embroider on white towels and i have never had a problem. Good luck and show us on Projects please.
You got your answer. Hoop WSS stabilizer, spray a bit of glue onto WSS stabilizer, position your towel for the embroidery and then place another piece of WSS stabilizer on top. When done spray the stabilizer (I just through mine in the washing machine on rinse) then you iron a little and PRESTO, ALL DONE.
Good Luck,
Michelle
