:)   Yes. Two boxes of blank cards, and about half a box of some punched ones.
Also thanks to a kind gift, a card gauge and a card saw. (No, I didn't know card saws existed either.)

And some boxes of blank paper tape rolls for the tape reader/punches - another project.

I'm on the lookout for more boxes of blank cards btw.
