Hi! New to this board w/ a question about autograph craft! :)

[Tigpooh]

Hey everyone! I just recently found the DISigns board and I think I am in love! I actually started out looking for some idea on making a cute autograph bag/holder for my kids on our trip in September. I have the books already and they are just made of cardstock w/ stickers of each character one each page for them to sign. It's super cute but I thought it would be great to sew a bag to hold the books in that could maybe be worn, with an adjustable strap strong enough to hold their trading pins. Can anyone point me in a direction to help me make one? I am sorta creative but not sure about trying with no clue what I am doing. LOL! Thanks for any help!
