I agree with Krista.
I once bought a stash of flowers that were preglued and had the stone in the middle, and the price was dirt cheap.
But after taking apart about 12 of those preglued flowers, I had enough. I normally sew my flowers after I take out all the plastic bits.
After I took apart the layers of the preglued flowers, I couldn't get all the glue off, so sewing them was impossible. I had to glue the layers back...I hate to use glue, unless absolutely necessarily
I can hand sew faster than I can glue, plus, it's not as messy
No more preglued flowers for me. I'd rather pay more for completely unglued flowers.
