Here's what I did and the result -
I found a cute little cardboard tag and noticed it was an interesting shape so traced the top part of it onto the bottom of my piece.
Next, I found some large buttons in my mass of craft supplies. It was difficult to choose which one or ones to use. I ended up deciding on the star and tracing it with one point over the other shape.
and then I traced the circle on the other side
Here's the string I ended up with to roughly guide my tangling.
I decided to stick to tangles I've been learning over the past week or so (and that's quite a few).
What a lot of fun that was!
