Here's a project I know some of you will be interested in making with your kids. This is actually my mums work (although I was a contributor) so I got her permission to post it here. Right up until about last year, Mum had a couple of boards with a road map drawn on with thick black marker for the kids to play on. Apparently I drew it way back when I was about as old as Aaron and Hannah. As you can see, the boards have been updated to a full-colour mat/blanket, though still with most of the original design. It's soft to sit on, and nice and colourful to look at, and it packs away easily when it's bedtime! I think it's made mostly by applique, with the road markings stitched on. It has non-slip rubbery stuff on the back (the kind you put under rugs to stop them slipping). It also has an inner padded layer, which might be batting, although seeing as Mum made, it could actually be anything in there ("make do with what you have"...).
Caleb and his cousin don't care what's inside - they think it's perfect.
And I love any sewing project that incorporates children's drawings!
