That's the level of craft I can handle these days :-)
It's SOOO satisfying for a hoarder type to be able to think of a use for those calendar pages that were just too pretty to throw away!
Some time ago I opened up a CD sleeve and copied it onto thin cardboard for tracing.
It took some trial and error (as you can see) to get a square just the right size, but once I have that, I can fold the flaps over it and they come out perfect every time.
Pretty, yes?
Unlike my larger dreams and plans, a craft on this scale actually ends up being made :-)
