x marks the spot!
I reckon I've got this year's Christmas gift sussed.
Embroidered & stitched entirely by hand so it's a good "kit craft" for taking along to kids activities.
I've used a couple of little stick on magnets (which I picked up at Reverse Art last time I was there) to make sure my handwork stays with the book & not on the tram.
7 OCTOBER - EDITED TO ADD:
I've just posted the tutorial here. Thanks all for your interest.
