I usually do a straight binding..but I'm just lazy that way. HOWEVER...a good stripe or a curved edging and its off to the bias with me. There are a few ways to make it...I will see if I can find a you tube link or something with pictures. (I'm a visual person myself!) I found a great stripe that was already on the diagonal! I got a nice binding without having to do bias.
