Hi Jmes4kids
Lots of good advice here. I just wanted to add that, like someone else said, lots of LQSs sell online too. You can even find sales online that aren't always offered in the brick & mortar. Also, there are online shops that sell fabric exclusive to them...you won't find anywhere else. My fave of these is hawthornethreads.com They have quality fabric and unique prints.
Don't forget that when shopping online you have to pay attention to the KIND of fabric you're looking at. Many sell knits, flannels, home dec and lots of other fabrics too. I once bought canvas thinking it was cotton. Used it for a tote.
And don't forget to enjoy......
