I made a quilt using fabric from sample books of home dec fabrcs from an interior designer. 100% cotton and glazed. THEN I used a thick loft batting. Threw the whole sewing machine out of kilter. Had to bring that one to the shop. Finally finished the quilt on my heavy duty "school machine." Actually looked nice after it was done. For the machne stitching in the ditch I used a wobble stitch. But regardless, NEVER AGAIN. I have a box full of charms that I made from the samples. They will go in a tablerunner or a wall hanging.
