Next step was to drill the holes...we had decided to use drawer pulls for the centers, so we drilled our holes the appropriate size to fit their screws....We did break a few glass dishes so practice with a spare. :) What we learned was to make a "guide" hole with a smaller drill bit and then re-drill with the larger one. ...Also there is a fine line between to much pressure and not enough. Oh yes a little water in the bottom of the dish also helps!
WARNING!! Only repinning to emphasize that lampworking is a dangerous activity, and (in my opinion) this tutorial is does not provide adequate information regarding eye safety, ventilation, nor annealing, among other things. Thanks @Kristi Swain
