Like the two for 1 idea on the table runner, never thought of that and then it wouldn't matter what bobbin color I would use. Really it's not a big deal to me what the back looks like but a couple of the runners are going to my sister who, let's just say I have a love/hate relationship with. That is the only reason that I want the bobbin thread to blend in with the backing fabric.
Thank you for all your help, you guys are awesome!!
