As a general rule, I try to frequent area LQS's. With that said, however, I'm really blessed (or maybe cursed?) because there are SO MANY here in the Carolina's. We actually have three different "sets" of Shop Hops - one for the western parts of NC/SC, one for the Central (Piedmont) section, and one for the Coastal areas. Each hop has between 13-18 shops. So, I have several that area either close by, or on my daily commute to work.
I also have a Hobby Lobby and Joann's in my area.
Then you have to also know that I have Mary Jo's (aka "Quilters Heaven") and Foust Textiles (a wholesaler that does "open to public" twice a year).
Occasionally, I buy online as well. But I try to frequent my LQS's so that they can stay in business.
The source does not determine what I make from the fabric, nor does it determine who gets the resulting quilt.
I have two grandchildren ( 3 years old and 18 months) and both of them have 3-4 quilts each already. Family members have several quilts.
I usually try to have "extras" on hand, especially baby quilts or children's themed quilts, for unexpected gifts.
And while I would be upset if someone gave one of my gifted quilts to their dog, I don't care how they use them otherwise - picnic, everyday, or whatever. I gifted them to be used. Most people who get one of my quilts are aware of the work and expense involved in quilting, so I seldom find my quilts in the dog's bed.
One that was gifted to a friend for her new baby, only lets him play with the quilt in such a way that it stays pristine (it's a "5 Little Monkeys" embroidered quilt). He loves it, and has learned his first 5 numbers and many colors from it. He's 6 now, and the quilt is still in like-new condition.
As a contrast, I made my very first quilt for my daughter when I was pregnant with her... and she uses it now for her baby girl. It's showing it's age and wear and tear, and I may re-do the binding when I'm there at Christmas. But I know that BOTH quilts are very well loved.
Sometimes, I have a particular pattern in mind for a particular person, so in that sense, the fabric is specific. But otherwise, it's just whatever pattern I like in whatever colors I like.
