I adapted an animal playmat pattern from this book by Laetitia Gheno (mentioned here before).
Adapted = used a sandy coloured background instead of green and added a volcano to make it look a bit more jurassic!
M's dinos are far too big for it but nevermind, he was very happy with it! And it folds into a little bag, so is quite handy to carry around everywhere!
Y quite likes the dinos too!
