A popular quilting style right now is quilting with your embroidery machine. And YES, I will be digging into this very soon and we have some nice large scale quilting designs in the works as well.
But quilting with my embroidery machine will always be limited to small projects, typically wall hangings. This is because an embroidery hoop is not designed to support the weight of a quilt sandwich (three layers: backing, batting, quilt top). If the quilt pulls the edges of the embroidery hoop downward, it could crash against the edges of your machine and really give you a bad day.
Using your embroidery machine for quilting is also limited by the space within the hoop. Anyone else find hoop sizes - inches and mm - confusing?
On a quilting frame like the Cutie Breeze Frame I'm using now, we have the same "hoop" limitation, but I can stitch approximately 8 x 29 inches with my Little Rebel on this frame before needing to shift the quilt to the side.
