Please help me with bracelet elastic, my child has got clay beads and made some lovely bracelets with the crystal tec 0.8 supplied which is slightly elastic. but we just can't knot it, you can't pull it tight, the knot moves down the string iyswim? and makes the bracelet very small if we even manage to tie it, DC is on the point of giving up. coated elastic thread isn't helpful as it coating unravels so you can't put the bead on. I'm thinking non coated elastic? please help I'm so frustrated myself now. thanks
