A draught excluder after all!
Thanks for all the suggestions for my cat panel - I gave up in the end as their tails got in the way! Wrapped around each other back and front meant that to cut them into individuals - or cushion covers, I would chop off tails and some would have two tails and some would be no-tail cats!
So, no quilting or patchwork, just straight forward cutting and sewing!
However, a certain three year old who loves cats with a passion will be delighted with this - I hope!
