You don't need to be a caning-nerd to truly appreciate the significance of these specialized tools. (But it helps.) See vid link at bottom.
Kaleidoscope caning generally results in round canes. Now, round canes are gorgeous for bead making and pendants. The thing is, if you want to use them for projects like cuffs and bangles, picture frames, journals, tins, and covering glass, you have to create triangular fill, which, we all know, breaks the symmetry of the design. That's why Pandora invented SquarePairs. Now, any round cane can quickly and easily be made square.The sides of the slices can then be aligned and fit together to create yet another pattern.
The set of six square tubes contains two each of 1" - 3/4" - and 1/2" hollow Lucite rods - 6" long.
SquarePairs convert your round canes to squares without distorting the design. You can now create kaleidoscopic strips and sheets which are useful in many more projects. Check out these videos to see what SquarePairs can do.
