AI want to try using straws to support my cake tiers rather than wooden dowels. Should I use the milkshake straws (1/4 inch in diameter) or tea/boba straws (approximately 3/4 in diameter)? Thanks for your feedback!!
The general rule of thumb would be the larger the bore/hole, the better. You get the most contact with the board that way, largest cake plug [acts like glue & a weight], etc.
If the boba tea straws are readily available, I'd use those.
I think a lot has to do with the size of the tiers. I always used milkshake straws. Worked just fine for me.
