I found this idea in the current issue of Australian issue
of Simply Cards. The cardstock is 16x30cm, and
concertina-fold at 4cm, 8cm, 14.5cm and 21cm.
I just added patterned panels, stamped sentiment,
die cuts, MS punch skeleton fern, paper flower and
the photo is my grandmother (I'm sending it to my
cousin in the US). It folds up very neatly and will fit
into a small envelope, easy for posting!
I'm entering this in MIM#149
