I used 4 mm Swarovski crystals, the holes are really small so I placed the beads using fishing line. The bracelet is very easy but there are a lot of beads so it does take a little bit of time. It is great for miniskeins or a special little bit of leftover yarn. I plan on making a matching pair to dress up the cuffs of a plain top. It is knit flat and grafted together after blocking. A really fun design
