Sewing and quilting is my hobby and should be fun and not an exercise in frustration so quality matters. I really believe in having quality tools, ie. sewing machine, notions, and fabric. In the same breath...I love a bargain too. I use coupons whenever possible and watch for sales to get the best for less.
I also save in other areas. I'd venture a guess that I have fewer clothes and shoes than most women. In addition, I save a cosiderable amount of money on food. Again, I stock up on things when they are on sale and make use of coupons. I cook and rarely use convenience foods.
In years past I had to shop price before quality. Today, our budget is larger, but old habits die hard so I always try to get the best for the best price. Quality doesn't have to break the bank...you just need to hunt a bit.
