I've tried Affinity Chickpea and was thinking of buying it until I found Krita. My trial period ran out before I could get the hang of it. I've tried GIMP too but I can't seem to get on with it. I find it quite confusing. I didn't know either supported SVG as well as Raster. I'm finding that really useful for making the map icons.
I put one of the works in progress on a Facebook wargames group I belong to in the hope of getting some of the labels interpreted and was surprised (and quite pleased) at some of the comments as a lot of members thought MY map was an original 1812 one and wanted to know when I would be making them available!
I'm finding cartography to be a wonderfully relaxing aspect of my hobby. Once I get so that I feel confident enough for the experts to see my work I'll post some on here.
