Some years back, I was about to throw away a large piece of packaging EPS when I noticed that it had squarish holes which could be used to make something. I painted the inside of these holes with acrylic paint & sprayed expanding foam in them. The acrylic didn't serve as a release as intended & I had to break of the packaging but I was left with 5 squarish pieces of hard foam.
Last week I was looking at them , musing if I should throw them away ( too much stuff /ideas, too little time , as a usual) & this idea came. Using packing carton shapes for fruit cut into roundish shapes & matchsticks I did this ( 4 to go ). Extras are 3d printed or card.
And now they are 5. In the last pic I put one used for melons on top of the 3. Quick, differently nice & effective .
