Most of you do this already I'm sure, or have a better way, but a friend told me I should post it. When cutting stripe ends running into another color etc. when you need a precise fit. I tack the stripe through the middle leaving the ends that will need trimming long. I slide a piece of clear plastic under the end of the stripe before I tack it down. This allows me to cut the stripe end with my blade matching the edge of the stripe underneath. Then pull out the plastic and tack the end.

That's a great tip Marv.
