The black beads were too small, the clear beads were too big, but I think the iridescent blue beads were just right. Having finished the grey with black, I thought there’s no reason I can’t use different beads on each side. The visual crossover is quite minimal. That said, when it was time to bead the neck of the tassel, I wanted to use both bead colours. I like random, so I would stab the needle into either bead colour to pick up a selection of beads and then pick a random direction to sew it down. If beads wanted to sit funny or bulge, I would go back and tack them down to the tassel bundle which also helped to reinforce the binding effect of the randomly beaded neck.
