Diagonal Seam Tape

Diagonal Seam Tape is simply washi tape that is placed on the front plate of your sewing machine to act as a guide while you are sewing diagonal seams

The tape is strong, thin, sticks well to almost any surface, and comes off easily.  Each roll has 10 yards of tape so it should last a really long time.
