I was thinking of something else and the thought "go forth and multiply" came to mind.
The word forth brought to mind 4th, with the 4 fully formed as seen here. So it had to be done. In the process, I've made the personal best smoothest fake circle yet on fontstruct, backed by a pixel-by-pixel matching of a real approximated circle in Ai.
Another marker-style experiment, this time with inktraps. The grid size makes for many difficulties, so some characters could be better (S, Z, e, x, etc.). Suggestions are very welcome for these glyphs, or any others. Thanks and enjoy!
5/16/14 S, Z, f, x, 2, $ and accents were tweaked by nudging. V1.1
1/30/15 The old, un-beautiful e and 7 have been fixed. Still looking for a solution for the 2. Also added Œ and œ. V1.2
6/7/16 Adjusted the 2 again; still not perfect, but better than before. Also narrowed the 7. V1.3
Stitch-y inline, bold outline, negative and a letter within a letter. Knitka (Нитка) means thread, rope. Thanks and enjoy.
