This is a copy of a card I made for an old schoolmistress a little while ago.
I’d got an old satchel in the loft, so I looked at the basic shapes it was made up of and cut templates, putting them all together for the finished card. It was a bit fiddle farty getting them to look right but after several attempts it all looked in proportion.
I made an A5 card in a red/brown colour and then added another piece ever so slightly wider to make the top of the satchel. To be honest the faux stitching makes the card and any blemish on it helps to give it a more realistic battered effect.
