Since you can't see well enough to re-position the needle in the original hole after pulling up the bobbin thread, I would simply hold the two threads to the back of the machine when you start stitching (so there are no tangles) and make about 4 tiny stitches. Try it out on a scrap sandwich first. I haven't done it for awhile on my 1230, but I believe I set the stitch length at .5 for those first few tiny stitches, then turn the stitch length up to about 3 for the quilting stitches. Before stitching, I always find both bobbin and top thread ends and hold my finger on top of them when starting to sew. This ensures you don't have a thread nest at the beginning of your stitching.
