Stage 3. Colorforms.
The next stage was making colorforms, basically. If you don't know what Coloforms are, you are too young and don't tell me.
I cut out all the base pattern pieces 5x each. 3 clear pieces and 2 frosted ones. (Some are extras in case I get screwed up, so I don't have to go back.)
This took a few hours, but was done this morning.
