that does not sound too bad, but I live rural and the nearest gas station is a 30 mile round trip.
I keep track of ideas, and then when I am out, I look for deals to get the supplies I'd be interested in. And if I get an idea and don't have the supplies on hand, it gets put on the back burner until the next time I'm out and about. Seems DH and I get into the "big city" of Sioux Falls about once a month, and they have two quilt stores plus a JoAnnes and Hobby Lobby. And if we are willing to travel farther, there are two more quilt shops not that much farther away.
If I want something particular and I don't need to match color, then I will order online. It took me two years to collect the 12 fabrics I needed for my sister's quilt, and most of them I got on a trip to MSQC. I buy for my stash when I find deals and am traveling.
