This is what I came up with.
I chose to do a stepper card as it's an easier way of incorporating lots of bits without detracting too much from the main bit of the card. About a hundred years ago (or at least 15 years) I bought some blank jigsaws and I have never used them - they were still in the original paper bag. I stamped and embossed the flowers on the front, coloured them in and then clear embossed the front to make it shiny like a real jigsaw.
Because the knitting bit at the bottom of the card was quite dimensional I had to make a box to put the card in. It was far too fat to go in an envelope and because of the way I'd stuck the pictures of book covers and the sudoku puzzles, it was way too wide as well.
Now comes the hard bit - what do I charge?
