The Bow Tucks pattern is VERY easy to make. I use 987F and Decor Bond (both can be bought at Joanns) in all my purses. It gives it a nice, sturdy finish and the bag doesn't flop when you sit it down. It depends on the look you want. I don't like flimsy looking bags and these two products give it a more professional look. You iron the Decor Bond onto the pieces first and then lay the 987F on top of the Decor Bond, use a piece of muslin as a pressing cloth, and iron it on.
