I ask myself, how often will I use this? If it's a ruler and I will use it to cut a whole quilt-it's a bargain because it saves me time and is more accurate.
On the special tool for clothesline baskets, if you are going to do a lot of baskets then it is worth it to you. I enjoyed making the baskets and used some funky rayon blends to clear them out of my sewing room. I have also seen some wonderful large purses using the covered clothesline, so get busy!
