I have tied many quilts, and for baby quilts or those I don't want large knots on I use embroidery floss. Depending on the color chosen, it can add a design element to both sides. One advantage is that for smaller projects, I don't have to get out my frame. I love to do cloth only (no batting) quilts about 45 by 45 for babies. I have given away many, and the people who receive them seem to appreciate them. ( I finally started remembering to take pictures before I give them away!)
