are you supplying the fabric? what about the patterns? your costs need to be included- is it simple patchwork you can 'whip up' in an afternoon? is it hand appliqued and may take weeks/months? you need to determine how much $$ you will have in it, then figure and estimate of time involved- then decide what your time is worth...and who it is for. I may charge a friend/family member just barely over what I have into making a quilt- for a stranger-commission job I charge a minimum of $20 an hour + materials...maybe more depending on the pattern- techniques, job involved- you did not really give us any idea what *kind* of quilt top you are talking about, or size---so, I would venture a guess of...between $45 & $500 depending on the project
