you took your length and width measurements and multiplied to get your psi...then you multiplied your total psi by 10 cents. and then you added to that total the cost of your materials (fabric, batting, thread, fusibles etc..) to get to the price you want to charge for your quilt. is that right? i ask because .10 is rather high for a psi unless your quilt is either really really good or your materials were very inexpensive, or you are including inthat .10 your labor. i ask this because i generally figure no more that .05 cents psi...otherwise i would never sell a quilt..and even .05 can be a tad high depending on the quality of the quilt...heirloom quilts generally are gonna be expensive but a good quality quilt that is gonna be used by the consumer and last awhile does not need to be too high in price. generally when i come to a final price with my figures...i still end up discounting total asking price.
