wonder under has been around forever! i think it was one of the first paper back fusables...i use it when ever i can locate it, it is not as stiff as heat n bond...even the heat n bond lite is kind of (stiff...it washes up ok) i think the wonder under is a better choice but that could be bacause it has been the one i've used most often....none of the lqs's around here carry it and our Joannes doesn't always have it. i have ordered it by the bolt in the past from joannes.com and used a 40% coupon for it.
