    Good tool to have on hand!

    The only thing that keeps this product from getting 5/5 is that I wish the manufacturer would add some sort of non-slip finish to the measuring edge. It's a super handy tool to have (and I wish I'd had it sooner), but it can be a little annoying when it slips on my paper as I am trying to measure a curve. Other than the slippery edge, I'd recommend this to anyone that works with patterns any day!

    So much better & more accurate than bending your plastic ruler to measure a curve.
