Lead in vinyl mini blinds
Just wanted to put this out there. We were looking at using some old mini blinds for our grid, but through some investigating found out there has been a problem with lead in vinyl (not aluminum) mini blinds. It looked like it was mainly in old blinds, so something to look out for if you're getting them from something like Goodwill.
From what I can tell the new ones should be fine (I haven't heard of any recalls in a while for lead), and are still super cheap.
