What sort of tape?
I've decided to make myself a weighted blanket with my birthday money. To accommodate my dreadful measuring/drawing skills I've decided to use a single duvet cover tartan pattern to follow the lines (slightly regretting not going gingham, but I liked the aesthetic).
I got some advice from my grandmother regarding reinforcing and she recommends using 'tape like bias tape that is not biased'.
Except, she was on the way to airport and now I have no idea what it is called and can only find the biased stuff.
What is it called? Could someone provide a link to an example of what it looks like?

Also, what colour thread would you use with this? I'm wanting to essentially sew squares containing plastic beads into it?
