You should always use bobbin thread in the bobbin--it is much finer than regular thread-it is either 50wt or60wt--use your walking foot and go for it--I would start out with straight lines and then crosshatch--good luck

I have used fusible batt for a couple of crib quilts, no pins, but very careful ironing to avoid permanent wrinkles on the backing fabric. Quilt very stiff; softened nicely after machine washing and drying before I sent them off.

For piecing I always use the same thread top and bobbin. And it doesn't have to match, just blend in like grays, creams, or white. Unless you are using a black in a lot of your quilt, then you'd want to use the dark gray or black.

Ditto on "Bottom Line" thread in bobbin. I love it; haven't used anything else since I found it (unless doing bobbin work). I have also found that Aurafil (sp?) thread makes less lint than any other brand I've used in the top. Good luck with your quilting ... an exciting new adventure!

I e-mailed Bob Purcell at Superior Threads to tell him that lots of Quilting Board members were lately saying how much they liked Bottom Line - he was delighted to hear it.

Thank you, everyone, for the very helpful information :-)

Welcome from Louisiana!
I use the same thread on top & bottom.

Welcome from Michigan,
I use the same weight thread top and bottom, however I do use different color to match the backing, it hides a multitude of sins.

Welcome...It's personal preference...I've used light weight(my preference) and same weight...There are no set rules...Try both and see what you like. :)
