children's building blocks fall over too easily and buildable structures are limited due to lack of block connections
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
About 1 in 5ish people will have some good modification ideas for you project.
good and plentiful tools make for faster and easier construction
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
Remember to twist, not pull to seperate
use smaller velcro
fabric blocks with a balloon interior (lighter, stronger, more versatile)
I made it at TechShop:
