Just last week I ran out of bobbin thread on the quilt machine just inches away from the end of the pattern (block). Then ran out of thread on my Brother machine with nothing to pop up and tell me I'm running out of thread. I was stitching the binding on the same quilt but I've learned on that machine to keep looking at what you just stitched every few minutes so you can catch yourself before you go along the entire side with no bobbin thread. Hate when that happens.
