thanks for all the repies!
I didnt use interfacing on the for 2 reasons. 1 it was my first bag pattern LOL! 2. i didnt have any and didnt know any better. i use interfacing on the insides of my wallet to make them sturdy....sometimes doubling up on it. i have used some REALLY thick stabilizer but it is really hard to turn. (this one was my 1st wallet ever
) once you put credit cards in the wallet it makes it pretty stiff and you dont really need anything special on the inside. THANKS AGAIN!! LOOOOVE THE COMMENTS
