What brand is best? I think I am going to use all white because the sashing will be white, or do I need to get another color to stitch blocks together that matches each block? Do I use bobbin thread or do I need to use same thread I sash with? Do you usually match your thread to each block color, mine are all different colors?? But sashing will be white, also anyone know where to buy the pre-wound bobbins that fit the ellure plus by babylock and a 1/4 foot and binding foot for free motion, and quilt clips?? Id like to but this all from the same store onlone??TIA
