It seems the older I get, the harder it is to stay focused.
Let me give you an example.
The other day:
I decided to get busy and work on my Posh Penelope Quilt. Haven't worked on it in months.
I had most of the pieces cut out but not all. I returned to it after Christmas and started cutting the remainder out. To my displeasure, I had forgotten how and had to relearn. At the risk of repeating myself, there is a ruler you use.
