This is really kind of a tricky recipe because it's like making bread.
You gotta make it a few times to get just the right texture. Also, cheaper
brands of glue may not work as well because they have too much water in
Combine approximately 2 parts glue to 1 part liquid starch. Stir it up and
it will stick to whatever you're stirring it with. If the mixture sticks
to your fingers, add more liquid starch. If it won't stick to itself, add
more glue. Store in an airtight container in the fridge. If you want the
mixture to get tougher and thicker, let it dry out a bit in the air. If
you get it just right (and I rarely do,) it will pick up newsprint like the
store bought stuff.
Silly putty is lots of fun to cut with scissors. Also use some playdough
toys with it, or ice cube trays, muffin tins, plastic strawberry baskets,
etc. Caution: This often sticks to clothes, hair, furniture. Wear a
smock and play with this stuff in uncarpeted areas! If you get it on
fabric, use vinegar to get it out.
