how do I view the video on how to use the block marker?

I have both sizes. My DD bought them for me as a surprise when she saw me watching the video at Nancy Notions website when it first came out. I use them all the time. Sure makes it easy to get perfect size blocks when you are doing a swap. I would buy them again if I lost them or they got damaged.

Click on the link and the video will start playing if your computer is set to allow video and sound.

I sure would like one, but I will wait until the price is more reasonable. 50.00 on sale is a bit too much for such a flimsy looking ruler.
