What a neat family plan!
Your DGD will love you forever for the life lessons you are giving her (and, of course, your other grandbabies.)
I could go on and on about how "imperfect" things teach personality qualities that the "easy" life never does, but by golly!
I'm wondering about the square being put into a hoop - - maybe that goes wonkier than the star? <g> But, I am not familiar with all the techniques you were working with, so it is obviously just a quick guess ...
Thank you for sharing!
