Many of us are also "so old" and have been at this a very long time.. quit beating yourself up.. I think it's lovely and you're doing a great job.. carry on!!

I wanted my center points to line up, but I didn't want to blocks to line up..I love the look of a traditional pinwheel pattern, but I wanted something a little more pish-posh, I never follow patterns..well once, because it all looks too uniform to my eyes. I like crazy quilts :)
I was always told pinwheels are basic for begginers..I dunno if I would agree with that, I had a really hard time at first, but as soon as I realized what I was doing wrong ( serves me right for not following directions or even looking at a pattern lol ) It came together very nicely...I'm hoping to get my borders on today, if my littlest monest ever takes a nap.

Very pretty!
