seed beads are actually sized differently, instead of using mm they give them sizes like 8/0 and 10/0.... the short version is the higher the number = the smaller the bead and for this I used 8/0 which work out to roughly 2-3mm
Hi, Any bead that will fit that dimention can work, which will be the majority of the beads we stock, we have a huge variety on our website so the choice is up to you the size of the bead whole can be find below Serinity Beads - www.bluestreakcrystals.com/pages/serinity-thread-hole-sizes Bluestreak x
