Can God make a rock so big he can't lift it? There's a paradox with no answer.
But I've definitively answered a similar question: I can make a pattern so difficult I can't sew it.
Okay, that's not entirely true. If I really, really wanted to, I could finish stitching my 'Garden of Epicurus' pattern. But as it takes shape, I can see that I'm not really happy with the palette, and after a few years of frustrating, intense stitching, I'll end up with a finished product I'm not really happy with.
So I'm letting it go. I've learned a great deal from this. If I were to try to re-do the idea, I'd limit the colors a great deal, instead of using so many different colors, and I'd simplify the shapes, as well. In other words... I'd do it completely and utterly differently.
For a long time, I felt like it was an assignment- I started it, so I have to finish it... right? Right? Giving myself permission to just stuff the thing in a drawer and never look at it again is very freeing.
Or maybe I'll just throw it away. How liberating would that be?
