I'm in my 50s and have memory problems. I love to paper piece but each time I go to pp I have to watch a DVD from Carol Doak's on how to do it. I have tons of rulers and have the instructions with each one, but I'm sure I'd have to find a YouTube video for more help. I'm very visual and seeing is what helps me. Maybe you are visual and need to be reminded of what you did. Our brains are only so big and they have over 50 years of memory in them. We can't remember everything. I'm remembering less and less the older I get. It's normal. Don't be hard on yourself. Take everyone's advice and look on YouTube.
