It's beautiful Ania! I totally understand what you mean about how hard it is....I just did a Storm at Sea test block, which decided us that we are now doing an Irish Chain quilt instead! (My friend & I are making a quilt for one of our "nieces" for her wedding.) I made it with paper piecing, but those points still didn't want to match. So it will get a couple borders & become a wall hanging for my office. :)
I admire you for sticking it out & finishing it! :thumbup:
