Looking to bring your hot glass skills up to par? Than try these to glass exercises.

1. Do your jack lines wander? One way to make practicing better jacking technique is to make caterpillars. Add a couple eye dots, flatten the bottom on the marver and you have improved you skills and made a little kid happy (even if the kid is you).

2. Try this jack line challenge. Make a glass chess set - the king takes 4 jack lines (looks like 5 marbles stacked on one another). The queen takes 3, (she’s 4 bumps high). The bishops and rooks are only jacked twice – pull on the bishops top one for a miter and flatten the sides of the rook for a castle look. The pawn is just jacked in the middle. The challenge will be getting the pieces that are duplicates (bishops, rooks and especially pawns) to resemble each other close enough in size not to embarrass you. But it’s GREAT practice and non to boring either.
