people always rave about my scrap quilts. i don't sell, i don't do commissions anymore either. but, if i were to venture into a help the sister thing ..i would scrap up my least fave fabrics, use up all least favorite scraps ..any block will create fabulous scrap quilts and be fun doing. and i think lap size will sell nicely. you may even fall in love with scrappys made from your least favorite fabrics!
if you don't have much money to invest in this adventure i wouldn't be making bags to sell ..the needed notions for bags such as the interfacing etc are expensive. even tho there are kajillions of free bag patterns on net that don't require things like zippers, snaps, or hardware for slides etc ...i still wouldn't put time & energy into making bags and expect people shopping in a craft store to pay enough to compensate you for your investments in time and money.
