Hello and happy Wednesday!
Today I thought I'd post a video of a Celtic knot construction. Have a go, they're a lot of fun :) Once you get your circles and straight lines in, you can make them as wide or narrow as you like. This is a basic design that I'm going to adapt with different colour schemes for each season.
You may also see why I am a new convert to a motorised eraser, which I thought was the most ridiculous invention in the world when I first saw one. It's actually an incredibly accurate and undestructive tool which I really love now!
