Thanks for all the info.
There is no Joanns here but I will check out Amazon, Canada and allbrands to see how prices compare.
Allbrands ships from the U.S. and that adds to my Canadian price.
I am tempted to get that Supreme Slider. My machine opens in the front and the piece that comes out, isn't flush with the rest of the machine bed. As I sew, the fabric sometimes hooks the edge where it isn't flush...jerks the fabric and needle a bit to one side. Do you think the Slider would help with that?
