Bastelkleister from the kitchen cabinet
I currently have a piggy bank phase and came up with the idea, which ones to make for New Year's Eve. So lucky pigs for next year.
First I tried it with bought craft glue. It worked fine, but went into the money. Unfavorable for my major project.
So I got from a colleague the following tip:
Take standard flour and mix it with water in a bowl until you get a mass that is similar to glue. Finished!
No additives, unpleasant odors, easily washable from clothes, hands etc.
And also totally cheap and environmentally friendly. So: on your marks, get ready, make your own!
