10 beautiful bookmark designs. Designer Banu Demirel says, "The number of strands used gives different effects with Blackwork designs. You can use two or more for a thick, rich look. These bolder lines will enable you a 3D look when combined with one stranded lines. I would highly recommend to experiment with variegated or overdyed floss as well as adding color to designs with solids according to your taste." On 28 count fabric, the design size is 148w x 178h (10.6" x 12.7"). Width of each bookmark is 26w x 86h (1.8" x 6.1"). 2 skeins of floss are required when 1 strand is used over 2 for all 10 bookmarks. See more of these beautiful designs below!
