I am making my first machine quilt and would like to know if I should use the same thread in the bobbin as in the top thread. Making the top has been fun. Putting it all together is scary.

That all depends on the top, the thread and other stuff, too! Can you post a pic and give us more details? The folks here love to help, but we need a direction to go in.

Welcome from Southern Illinois.

I use a lighter thinner tread in the bottom.

Hey from NH!!!!

I don't machine quilt anything larger than a lap quilt. When I do machine quilt sometimes I use the same thread top and bobbin; I am devoted to Bottom Line in the bobbin (the bobbin lasts forever) Always have it in the bobbin regardless of what top thread I'm using.

Hi & Welcome! I cant help you on this one, Im a hand quilter.

it is your choice, especially if you want a different color for the backing than the top; it also depends on your machine, sometimes the machine just behaves better when the threads are the same, sometimes it doesn't seem to matter. i would put together a small practice piece, sandwiched and try it out with the same and with different threads so you can see how they are going to interact. (be sure and try the threads you want to use to see if they will work.

Hi and welcome from the sunny state of Florida!!! I'm a hand quilter for the most part. I've only SID on baby quilts and I used the same top & bottom!
