Over the last 30 years, I have experimented with almost every craft possible, usually focusing on ones that take some degree of technical skill. Lots of trips to the library enabled me to learn the basics and time and practice took care of the rest. Some of my favorites include scale miniatures, woodcarving, scrimshaw, and lost wax casting.
About 8 years ago, I discovered gourds, and it was an immediate addiction! Here was a craft that combined many of the skills that I had developed over the years.
