As I was wandering through some quilt magazines passed on from a quilty friend (Thanks Nancy!) I found an ad for a quilter's chalk line. Now they want 17.95 for the marker and then quilt chalk over and above that... But the ad does refer to "borrowing the idea from the hubbie's toolbox" Well yea....
For about 8 bucks you can buy a snap line thingie at the local hardware store and fill with quilter's chalk. It would make nice straight lines for quilting or lining up longarm quilting areas...Genius!
