Thanks all.
Buenchico you've found some I didn't find. I found the oval one before (think I spotted it on eBay not Amazon.) I like it and the cactus one - both would suit the recipient.
I found plenty cat and puppies, but they were not "the recipient".
The best range seem to come from China. Some of the Chinese sellers I found on ebay don't post to my postcode, but spotted that some of the Amazon ones are supplied by Amazon which is good.
Etch - I had thought of that, even found a site to generate a pattern from a photo of their dog, but the beauty of a kit is you don't end up with loads of extra wool when you only need a few strands of some colours!
Had looked at Readicut - I remember them from the 70's.
Off to visualise the sizes (and charge the ipad!)
