Here is the link to a really good crafts activity for kids, the elderly or for yourself as well as being inexpensive, attractive and great for the environment.
You can also make these for any time of year, not just for Christmas decorations, out of any greetings cards you like, to hang around your home or in your child's bedroom. Make the circles smaller for smaller versions or larger for larger versions. I use tacky glue for these as it bonds quicker and the circles will stick with just a short squeeze between your fingers without the whole thing falling into it's pieces. Normal white glue ( P.V.A.) is a disaster to try and use!
All the Best and Happy Crafting!!
