Sisita, I used CK gumpaste mix. It was only $2 or so. I just followed the instructions and just added 2 TBSP of Tylose. Then I when I'm about ready to use the gumpaste, I take a little and I knead fixodent in it.
Momkiksbutt, I heard you can use the fixodent as a tylose replacement. I heard fixodent is the same thing, but it has that mint smell. I haven't bought the wilton one. I just use the CK gumpaste. I think I can find some around here in Hawaii, but I haven't gone to Excutive Chef yet to look.
Thanks to everyone for their compliments!
