I've been taking steps to specify the type of crafts I wish to do, as I've got way too many skills/hobbies (not to boast, btw ^-^;; ). I picked two to concentrate on, ceramics and wood turning. I chose these two because one can make almost anything within the same category. So I won't get bored or be less likely to procrastinate on finishing something. I also intend to do various of other arts/crafts, depending on what I can dish out at the time. So things may be a bit random, per se, at times.
I don't have any plans on "mass producing" things (unless ya count digital downloads). So for physical items, the most I'll ever make of any particular item would be up to 20 at a time, and even then there may be variances, since it's handmade. Most of the time I may go for 5-10 of the same thing/style. Once gone and/or I have no interest of making them again regularly, they'll only be available for commission or on some special occasions of my choice (limited, of course). If something I make is popular enough or I intended it to be a regular item, I will put it out more regularly, but it'll be made to order and only so many at a time. So shipping time will certainly vary in those cases. I'll try my best to give as close of an estimate as I can. Starting off, I'd rather do premade stuff, but over time may accept commissions or made to order items.

*Unless items specifies a collaboration or made by another artisan entirely (which I may do for my close friends etc.), everything is made by me. Items that are made-to-order/custom/commission will have varied shipping times, and again, I will try to give a close estimated time as possible.
Premade/ready-to-ship items will have a shipping time of 1-3 business days.
