While I was on retreat last weekend, I noticed my machine was a little noisier than usual in the bobbin area. Upon closer look, I found that one side of the plastic bobbin race cover was loose and the rivet? that had held it in place had fallen out. With a little help from a friend, we patched it back together but as soon as I got home I ordered a replacement. Hopefully, it will come tomorrow and I can finish the rest of this month's blocks.
