Remember the Twister tool?
 

Decided to used the twister tool to make some quilts. Have the books but really don't tell me how many charms I need to make quilts approx 36x42 including boarders. You guys remember these quilts. Can you help?

I would make one block to determine the finished size, then do the calculation from there for how many blocks you need for the size you want

I remember the twister quilts, but I never had the tool. I think I'd do what LAF suggests.

If you have the small twister tool and use charm packs (5" squares)., The block will be 3.5". I'm working on one know. I'm doing a Queen size. I did 23 squares across and down with a 3.5" border around. I'm adding a second border after cutting and sewing the squares. My finished size will be 86x86.

Queen, just the number I need. Now I can put a stitckee on my books. TUSM

I made a lot of the twister quilts. I think have about 4-5 different sizes twister tools. I never made the smallest one. I made one queen sized and several smaller table runners. They were fun to make. Enjoy. Just remember that the larger ones take up a HUGE amount of spaces before you cut them into the twister....I would if you could work them in sections somehow?

I always liked the looks but, never bought the tool for them.
