This week's challenge is to use only straight lines on your tile. You can use tangles that have only straight lines, or take a tangle that has curvy lines and make it straight. This is harder then it would seem, and it made me realize just how much I do use curvy lines. I decided to make Auraknot with all straight lines (which was hard to do) and then around it I made Printemps (as round a tangle as I could think of) and made it with all straight lines. Good challenge, but bring back the curvy line!
