i have been asked to make a few prototypes for a possible larger order of custom goblets. i am decent at making goblets, however i am under time restraints and low on the right materials. i have tons of glass, only thing is all of my tubing is either too big or too small compared to what i would prefer for the cups, plus its all heavy wall. i found these on glasscraftinc, but wondering if anyone here might know someone or somewhere cheaper? thanks for the help.
