I needed to write a couple notes today in a notebook and found these little beaded beauties from long ago. They were cut from larger notebooks but you can easily use a full size notebook.
If you want to make one, just unwind the spring coil from a notebook and add beads as you put the spring back on the pages. Don’t fill each coil all the way with beads or the covers won’t be able to open fully. Add a few rounds of beads and test how the notebook opens before completing the beading.
