At the last Multiples Club meeting, we made change purses out of duck tape, which was easy and fun. There were some boys of the age range of 6-9 there, and they totally got into it too, so this craft is kid-friendly. The only supplies you need is at least one roll of duck tape (I got mine at Walmart), some sharp scissors, and a ruler.
First, measure out your duck tape. You will need to decide if you want to do a multi-colored purse or solid. For my example, I'll be doing dual colored.
Measure out 4 pieces of tape 7 inches long.
Measure out 1 piece of tape 9 inches long - this will be the color you want the outside to be.
Lay down one color sticky side up, and cross it (as close to the middle as possible) with the other color piece.
Now put the same color down.
Flip it over and put the same color down on back.
Fold the side up so that it is the color you want on the outside. Don't worry if you have some uneven edges.
Start wrapping your 9 inch piece around the outside. I start slowly with one side. You want to try to do this with no gaps in the sides, so that it is tight.
Once it is all wrapped, it'll look like this, and you'll trim off the edges.
So then your box is nice and even:
Now you will go around and fold down each corner. Make sure you go the same direction on each side.
When you fold, stick your finger inside the box and work the inside well, so your creasing will be strong.
Once you get all your creases made, start twisting the top of the box, so that it will collapse on the creases.
And twisting a little more:
Ta da! Now place it under a heavy book for about a week, so it'll set.
There are all sorts of fun combinations, and you can get many different colors of duck tape at craft stores.
These would be great for the pool, as you could tuck in a couple of dollars or some change, and the duck tape is impervious to water.
Don't want to make your own, but still want one? I'll be happy to send one to the first 3 readers who comment, saying they'd like one.
