Thank you I might use this idea for some other templates along the way.

Good idea to make one - I just asked dh and he said he has some plastic and he will cut one for me. :)

I don't want to take up too much space with this thread now, but if someone could just tell me simply, what size should we make the square? And what is the measurement from the corners to the lines? Each side would be the same, right?

I'm sorry, I know I can find all this, but I'm having a hard time actually focusing on what I'm reading! :oops:

Oh, and thanks for the kitty support. As all of you animal people well know, it's inevitable that we face some awfulness as they get older and sick. I just hope I can do the sq fluids.
