First of all let me say that I am in love with the envelope board from We R Memory Keepers. Stampin’ Up also has one available. The is a gift bag I made using the board. The You Tube can be found here.
I followed the directions for the bag exactly except when I made my bag I put a band across the top that was only glued on the sides. I then put a brad in the flap so that it would catch on the band to hold it closed.
