Tips and Trouble Shooting:

If the gap is too small to slide pieces together, you’ll need to widen it with either a diamond file or a diamond bit on a dremel tool. Use plenty of water and wear a mask.
Make sure the feet are level, if your vase isn’t balancing, you may need to grind the feet larger and flatter
If your fiber paper doesn’t come out cleanly, add water and dig it out with a skewer or hooked wire.
Yes, the vase can hold water
