some people use the X's 3 formula for figuring a price- as in keep track of all expenses- then multiply by 3- and you should come up with a pretty 'fair' price-
remember to follow copyright laws- keep good records- label them correctly/honestly ( some states have laws concerning selling textiles- the fiber content has to be on the label- (as in 100% cotton/ polyester batting/ect.)
it can certainly become a (job) instead of a hobby if you let it-
if you just make quilts you want to make- then show them off- and people want them- sell them- it can easily make you extra $$ (support your quilting habit) without becoming a job-
if you start taking special orders & trying to quilt on demand it can quickly become quite a chore-
there is a site on line called: Quilts For Sale=
they are 'based' in Canada--with a couple hundred quilter members from the U.S & Canada
browse the site- you will get an idea what quilts are selling for- you can sign up for their newsletters & then will see when new ones are added & when ones sell- so you can really see what is selling & for how much-
best way to start is to show off a quilt & if someone offers to buy it-give them a price- if they buy it-cool - you are on your way. it can be as big a 'head-ache' as you let it become- or simply a way to support your habit and still love what you are doing. good records & organization is a must though...keep all receipts- start a quilting journal---take pictures- keep track of the time you put in & don't forget a new needle for each new project, thread- piecing & quilting, ect---
