Penny Floor - don't know if I would have the patience for a whole floor. but a coffee or patio table would be nice! Also an easier way to do it is to put out the pennies then flatten then by, I don't know, maybe a broom or some thing.
This would be a great idea for those times i need the large cutting table for those incredibly big projects aka backdrops and wedding formals. Floyd Leg - clamp-on legs (available in 5 colors) works with material up to thick.
