I am making a pirate outfit. I need to make a simple spyglass for it. I am opting for no sew but if I have to I will sew stuff I need for the outfit. This isn't for Halloween, just for fun and I like pirates so.
I only have cardboard and paper and fabric(I suppose I cold knit myself a square and tie it or something since I do have yarn) and the only source I have of cardboard tubes is toilet paper and paper towels. I don't want to waste them simply to get my tubes needed.
However I will store these tubes in a box so that I can use them. I have tape and glue to stick them on with. So how many cardboard tubes will I need to make the telescope and of what sizes?
