I love the block; how do you make it? I would love to know; Mariah.
To answer your question about when to quit worrying about it being not good enough and when to quit ripping; I made a 4-block Log Cabin Wall Hanging recently. Somehow, I got darks over onto the very edge of where the light should be. I hand quilted it that way, and never noticed.
When it was done and framed, of course, I saw it. I was going to take the entire thing apart. My friends said to leave it; "call it your humility block." So, that is what I did, and it is hanging in my front hall.
I think we sometimes expect too much of ourselves. I know I do!!
Mariah.
