Yesterday I was hiding my thread ends using one of those self threading needles. Of course I frown (read can't) on using thimble. I start out using one two stiches later I need to take it off. Sooner or later it stays off. Didn't think I was jabing my finger, of course I was. So last night I put some Blistex (for cold sores) on my finger tip. This morning it was almost better. My new cure all. LOL.
