G'day doydie, how are you doing?

I'm sure there are other ways, but the only way I know of making the oval shape is with Microsoft Picture It! Photo 7.0 (that's the one I have, but I've not used it yet). I need to go test it out later to see how it works. Do you happen to have Picture It!?

Edited to add: Yes, I found some oval frames in there but am not sure how it all works yet. Never used it before. I think it's part of Works Suite.
