I love the idea. I am going to start saving right now.

It was a sad day when I found a bird dangling by his leg by a thread one day in my back yard. It was a hot day and I noticed the bird hanging upside down and fighting to get loose.I was able to hold him and cut the thread loose from his leg.So,I would not recommend using the threads.

I used to put out bits of thread for the birds, then I read somewhere that it was not a good idea. The birds put the threads and scraps in their nests and it draws attention from their preditors...making them easier to find. Maybe dark colors wouldn't be so bad.

I have heard of doing this, I think I will start trying to save mine.

What a fabulous idea! I save dryer lint for the birds, now they can have another option. Its kind of like Home Depot for birds!

What a great idea! Yes i will start this tonight!!!! Thanks!

Yes, I put the thread outside on my grill table. great idea about the onion bag. I will do that next spring. :)

love this idea, the birds must love it.

Great idea!

Thanks for the idea. I will try this but will cut short...another great tip.
