Hi. I drew a very rough initial fountain pen sketch in a sketchbook, photographed it on the iPad and imported the photo into Designer. I then used this sketch as a template for creating groups and layers for all the parts. I always try and group/layer everything so that I can easily move or hide elements. The process is more fiddly on the iPad than working in Illustrator on a Mac with a drawing tablet but the results were well worth the time and effort. I currently find Procreate a better app for sketching with than using the pixel mode in Designer, is is just more efficient. However, I need to explore it more. It is just a matter of sitting down and playing, or finding a challenge to get excited about.
