Here are three detachable collars I made today. The collars were a quick project taking just over an hour to make the three. I still need to sew button holes on all three collars. When it comes to button holes I generally procrastinate sewing them, so my plan is to sew at least one button hole a day. With the collars and all my other projects I have 18 button holes that need sewing. So I should be done in 18 days.
