Felt!

                  

 Looks confusing? This is the map to something young children will love: A little felt fella who walks about.

Here's one I made earlier

First cut out the pieces - 1 body, 1 pair of trousers, 2 boots, 2 soles, 1 hat or not.
Cover 1 big and 2 small balls of wool/stuffing material/styrofoam in fabric, tie off the "hands" and the "head". They are ready to use.
Fold over the body and sew up, leaving the openings for the hands. Stuff with material (old tights would do) and push the hands in and attach. Push the "head" through the X-opening at the top and attach.

Sew up the trousers like this: Fold from the outside in and attach in the middle. Leave the openings for your fingers.
Close the boots, sew the soles onto the bottom, stuff slightly and slip over the trouserlegs to attach.
Now the straight upper edge of the trousers can be sewn onto the backside of the body. Be sure to leave the finger holes open.
The finishing touches are some wool or similar as "hair" and a hat or bandana or whatever takes your fancy.

Tadaaa!

(Felt is available from Hobbycrafts in a wide variety of colours.)
