Hi Leonie, I just found your site by accident..........and have been here for the past couple of hours!!! I have a couple of tips for you that i came across by accident.
Tip 1 :; When you've removed all your peel-offs from the backing sheet, you have the bits that divide the strips left. These can sometimes be used as peel-offs in their own right, as long as they are not too big or wide.
Tip 2 ::, I know it's probably a little late for this one now, but then again maybe not. Next time you go to your local supermarket, ( usually one of the bigger type stores)have a look around in the clothing section. At this time of year especially lots of them have loads of sparkly jewellery at very very low prices, ( I paid £2 for one of the necklaces!), which are just perfect for pulling to bits to get at the " jewels" in them. They give you lots of different sizes of the bigger gems/jewels that we find hard to get hold of, and are in lovely colours. That way you have lots of them, for little money, - and come "sale" time, they may be even cheaper! I Hope these help.
