Thanks for your lovely comments. The letter tiles are made of foam and were bought from QVC (they were in the clearance section a few weeks ago) and I couldn't resist them at the lower price, you get 26 packs with 4 letters in each pack. I've never seen them anywhere else which is a pity I'd like some more m's.

I shall also pass on all your good wishes to mum when I see her on saturday. Thank you.
