Calculating Wholesale Pricing

Hi, I have a question I need help with. I have been in the wholesale
giftware business for about 15 years and started a jewelry line
about two years ago. However I swore I would not sell the jewelry
wholesale but am now coming up to a show that is wholesale for my
other giftware (still handmade) and will have my jewelry there. I
used to do 2x markup and realized I would not make any $ that way so
took the terrifying leap of 4x materials and so much for my time.
And now that I see the picture am wondering how to do wholesale from
that 4x=time price. If I go 50% off, then I am only making enough to
make another piece and was paid for my time. These are one of one
pieces.
