I was able to cut them all from a half sheet of 5/8 particle board.
It would have cost $375 to buy the forms pre cut. I have about $9 invested in the particle board.
I know they say that time is money. And it took a lot of time to lay out all the forms and cut them out. But I have lots of time and very little money. Besides, It makes me feel like I have accomplished something good.
