Velcro Building Blocks Made of Cardboard

Problem/Gap:
children's building blocks fall over too easily and buildable structures are limited due to lack of block connections

Solution:
Add velcro

Materials:
Purchased from "tempe sales"
5 yards hook velcro ( circle ), $1.50 a yard
5 yards loop velcro ( rectangle ), $1.50 a yard
cardboard boxes $0.25 each from craigslist

Ask for advice/suggestions from others(Mitch is good).
About 1 in 5ish people will have some good modification ideas for you project.

Cut velcro
good and plentiful tools make for faster and easier construction

Apply velcro symetrically
make all blocks with the same pattern (this prevents mismatched connection surfaces).
An added benefit of using circular and rectangular velcro is the creation of facilitated thinking.
I tried rotating the image 180 degrees and could not get it right side up

Build something

Strong joints

Remember to twist, not pull to seperate

possible improvements:
use smaller velcro
make corners
fabric blocks with a balloon interior (lighter, stronger, more versatile)
