Apologies for my long-windedness here, but my sister from the Windy City needed to replace the windcatcher for a wind chime our Dad had made her. She suggested something in a celtic knot design and about 6 inches in diameter.
Looks awesome! You might check out defocusing acrylic engraves, it apparently makes it look much smoother. I haven’t tried it yet but I’ve seen posts here.
I accidentally defocused a score recently laying out something without the crumb tray. Since scores are faster than engraves, that might be something to try. Except that you would have to draw the lines.
