I use carpet tubes with wooden disks screwed into each end. I then wrap them with packing tape. I put the bow in a wool bow sock, then tape those air pockets around the bow until the thing fits snug. Not the bubble tape, but the ones that resemble the size of a hotdog bun. I also pack each end with them, along with packing foam, so a sudden drop doesn't hurt the tips. I ship via USPS Priority Mail with insurance and delivery confirmation. Hasn't cost me over $25.00. The PVC pipe and caps are the easiest, though. Just adds a bit of cost to the shipping, as carpet tubes are free.
