I have been selling on e-bay for over 4 years; I make miniature or doll quilts and have done fairly well. Buying and selling runs in cycles but even if you try to sell just ONE item that you have you will find that it is pretty easy. Look on e-bay or etsy for items that you have and see what they are asking; watch an item and see what it finally closes for to give you an idea. You can do the auction style or the buy-it-now. Figure out what your shipping costs are ie - postage, packaging materials and how far to drive to the post office, this will be your shipping fee which the buyer pays. Be sure to list for international; shipping is no problem just a small custom form to fill out which is attached to the package. I know this because I have sold in England, France, Korea, Holland, and Australia. You will need to sign up for a Pay-Pal account to accept funds on e-bay (this is now their requirement) but that is easy and can be used to pay your fees to e-bay and you can easily transfer funds to your bank account when needed.
Taking needed meds is far more important than stashing in the closet items that don't see the light of day. You can always sign your work and that way years from now your name will be remembered.
