A while ago I was asked to make a dinosaur play mat for a friends son which ended up as a sen bag which could be taken on holiday etc and had pockets to carry his dinosaurs as well as his name on.
You don't have to be able to sew to produce a play mat that your child will love. Here I have used scrap pieces of fabric left over from past projects and some very strong child friendly fabric glue. The various textured fabric pieces add to the sensory play element of the play mat. Mountains, rocks, palm trees, a river, a drinking / washing pool and a place to roam as well as a volcano of course. Just add dinosaurs : )
