I've been in the process of completing a very large order (large for me). Mostly the trouble was in the details.
I received an order that include a bunch of acrylic pens, and I just don't turn acrylic much at all. It was a nightmare. Chip-outs, cracks and breaks.
In addition they ordered some bracelets but they wanted them a bit larger than I had been making them. So... yeah. It was a bit of a learning experience, but now that I'm all done I feel great!
They're all completed and delivered as of last Friday. Hopefully they sell well and I can put my new skills to work making more...
