Only when I run out of spider thread, and it's a crappy experience. Tying roe is an onerous enough chore as it is! I have used everything from thread to dental floss. Spider thread is the worlds greatest invention and gift to roe chuckers!buck said:has anybody ever tied roe bags using coloured thread? Like if you were using orange mesh you tie it with red sewing thread, I think it would look like a blood dot
