How can we utilize an empty tissue roll in an interesting and innovative way?
Apart from making craft with them (as Anum suggested), if you know someone who has a hamster or mice you can give it to them for the pets to play with. The pets will appreciate it.
I have used them for Christmas decorations. I created the idea about when I was 8yrs old. My mother was having a hard time right before Christmas and we had no decorations for the tree. I used the rolls to make them. I first gathered up the rolls, some tacky glue, twine, material. I cut the rolls into three. Measured the material just 1/8 inch wider than the portioned roll. placed the end of the roll portion on to the material and traced a circle around it, repeated it enough for all portion ends, cut them out, glue the material to the portions, let dry for a moment, trim cut the excess off, measure twine to cover rough edges, use thread to create away to hang.
