We are going to have a go at Iris Folding this month, something I haven't done in ages.
When I first had a go many moons ago I used the inside of envelopes for the papers and amazingly this can be quite effective.
I used simple shapes to start with, like squares and ovals. I even did some dry embossing on the corners of the oval one.
I progressed to more complicated shapes all cut out with a craft knife (in the days before the Cuttlebug).
Simple Christmas trees can be made with triangles too.
Any aperture cards can be used.
I also did some cards from a kit.
I wonder what delights will be created this month.
