I use wine bags for my albums because I get a bigger finished size and they are nice and heavy bags.
This is a picture of the insert. I have 6 of these in the album.
I plan to put this album on Etsy and see if I can sell it. This is a new thing for me. I have two albums on Etsy right now. If you care to check it out, it is under friendscrafttogether (a site I set up for Tina and me to sell our craft items). If anyone else would like to try selling on Etsy feel free to contact me.
