What a lovely idea!! And using linen is perfect! I love the look - both of your patches and your inspiration's darning. I recently repaired a little news-boy style cap that I'd crocheted for my youngest daughter, when she was a toddler. She found it again, in my things, several years ago and at 20 something, was bummed that it didn't fit, anymore. I laughed, and told her I'd make her another, if I could find the same
thread, and when we found a hole in it, she asked if I'd be able to repair it, so she could have it for her someday baby.
Early this spring, I finally found the thread - an exact match! So, I bought two balls, repaired the little one - almost unnoticeably, and started another, to fit her, now. I'm struggling to get it to " make it look just like the little one? Please?" because it has to be so much bigger! I'm working on it, but can't get it to lay right - yet. But, both of us really have trouble getting hats to fit properly, because our heads are small and oval, not round, like most hats seem to be made.
