the key to...

I bought these keys at Ludlow market, and am planning to put them in one of those deep frames, just as soon as I can work out how to do it. I have a craft evening next Tuesday so I may well hope that one of my clever friends will show me how. I have tried what seems like all the possibilities of putting it together - clearly I have missed at least one. Do iI need to mention that it came from IKEA?
I am feeling distinctly grumpy tonight, brought on by the cold weather, I think. It just makes me feel that I don't want to do anything! Let's hope tomorrow is better, both in terms of weather and temper.
