IMO, all pieces look/feel
IMO, all pieces look/feel better with at least two layers of glass.
I’m not certain I understand what technique you are using for a “bud vase”. Generally, the lower the temperature you drape/slump at, the better your results.
For draping over a floral former, I typically don’t go above about 1225. For drops, I start out at that temp, but often kick it up a few degrees after a while (that could be my impatience!)
