This is our new toy! Looks like an instrument of torture but in fact, it is a little engineering gem! When you attach it to your sewing machine, put material under it and press the foot pedal...it whizzes off, turning the material as it sews. It sews with both straight stitch and zig-zag variations creating different patterns as it goes. (Tricot stitch works particularly well.) It was quite mesmerizing when we first used it. We have only played around with it once and these are the shapes it created!
There are three concentric sizes of shapes it can produce, the largest being just over an inch in diameter. With the combination of size and stitch, you can create various flower shapes. Apparently, you can create a circle of petals too (as in a daisy!) by using the transposition method but we only managed to achieve this once - more by accident and we haven't managed to recreate it - YET!
We tried both a solid colour cotton and then, the variegated gutermann thread that changes colour as you sew - the effect even when using the same settings, was quite different, in a good way!
To prevent puckering of the material, they recommend you use either two fabrics together or use the stitch-n-tear stabiliser on the back. As we don't have any of that, we used a medium weight iron-on interfacing, this worked fairly well but we will consider buying some stabiliser when we're next able to shop! (being unable to drive with my plaster cast on my arm is rather inhibiting not to mention annoying!)
