I found this in my inbox this morning. It’s from the Make: newsletter.
When prototyping perfboard layouts, long component leads can be a pain, sticking out on the underside of the board. I don’t want to cut them off yet, because I might need long leads. Solution? Green florist foam. The leads stick into the foam, which holds them securely enough that you can turn the board over and nothing will fall out. But they’re also easy to pull out and rearrange as needed. [Sean Ragan]
