I like these better, mostly the bottom one. Could you try altering it with these guidelines? First to make the part sticking out on the right side (top of J or inward part G) symmetrical, now the inner side is longer than the outerside. Second, slightly increase the width in the horizontal curves at the top and two in the bottom.
When the basic shape is done, I'll try using a few filters or textures in different colours to create the graphic for the sweater.
Thanks a lot though, I hope you don't mistake my 'complaints' for being ungrateful.
