I made cradles for my tamas a little while ago and I thought that I would tell you how to make 1! I'm sorry but I can't show you a picture of it! I alwayz put the cradles next to the computer so that I can just look at them side wayz to see if they're ok.
Ok, this is how you make 1:
Cut out cardboard that is about 28cm in perimeter.
Then, on 2 sides, opposite each other, cut it in two places like this: ______________
l l
l____ ____l
l l
l____ ____l
l______________l
except more equally.
Then, you'll have six places that are cut up, three on each side.
So then, you match them up and you staple them together, then you put a bit of material in the cradle or some UNUSED tissue paper and you're done!
