It worked

So yesterday I played with this iron on stuff, and today,  pushed into action by your encouragement, I took a pair of scissors to it

I cut along the solid lines, cutting it into squares

















I then cut diagonally along more solid lines

And with a little apprehension, I opened the block

And found a pretty darn perfect HST

Good job I made lots of them

 

 So the next question is: what am I going to do with them?

And the question after that ... what was the stuff called in case I want to make any more?
