Yep

But rarely get the time
I'm very lucky to have a friendly jewelers' supplier who is prepared to sell me gold, silver and gemstones in the ridiculously small quantities I use.
This post hit a nerve

There is this
thing around that anyone who makes fancy ornamented stuff is an amazing artist. Drives me mad

If you've ever made a model airplane/boat/train etc as a kid, you most likely have many of the necessary skills.
The principal ingredient in reality, is simply the will to 'have a go' and be prepared for a few mess ups until practice works it's magic

No harm to have some idea of form & style too, but that's not all that unusual.
The biggest danger IMHO is avoiding bling.
Steps down from soapbox
