Steel Wool pin cushion

Found this on Pintrest. Anyone ever tried it? Making a pincushion and stuffing it with fine steel wool to sharpen pins and needles. There's some discussion about not leaving pins/needles in it for long due to rusting. Here in humid Houston...that might be a problem, but evidently those who commented said it was not for them. Here's the link:

wonderful idea !!!!

Ive read about it before but would be concerned about it getting wet at any stage and rusting which would ruin the fabric. I know I wouldnt be the only one to have a coffee cup or glass of water knocked over when sewing. I wonder if they really sharpen the needles, seems a lot of people make them

I"m really curious....may try it, but keep it on the bookcase behind me...not where I put drinks! Good observation!
