I decided to make a full sheet of my camping themed 'doodles' and you can click below to get that too.
Paper - Camping
I used a sheet to line some envelopes so I could make a matching set of stationery.
To line the envelopes, just turn your page over, use an envelope to outline your basic shape.
Cut around that but inside the line by about half a centimetre.
Apply glue to the back of the paper and pop it into the envelope.
