I have designed and made my friend a birthday card for December. I made a box section and covered it with a cut-out picture frame. The tatting in the centre is covered with acetate and so does not show up very well because of reflection, but in real life it is quite effective.
I saw this type of card being made on a TV craft program and thought that I could replicate the idea without going to the expense of buying the kit. Luckily I had all the equipment necessary and it wasn't all that difficult to make....just time consuming....and I think it turned out well!
