Mine would not lower this a.m. either and I found out that my quilt guide was stopping it from lowering. I was quilting the bottom of a bow tucks purse and I'm happy that I've got the outside of it all done. Now to go make the straps, but will have to see if I have the right fabrics for the lining. Hope you get your machine fixed in time to get that quilt done. Huggies, Fay
