I need to find a 4 in wide cardboard tube to make a mold box for a sugar wine bottle. The biggest tube I can find at the post office, postal stores, etc. is 3 inches. This would work fine if I was making a mold of a beer bottle, but not quite wide enough for a wine bottle. Any suggestion? TIA

hi, i have just made wine bottles and i bought from a cheap shop a christmas tube. hope u have fun. i did!
