Here's what you should do:
- Scan your work, one glyph per file - from here on the instructions are for each glyph separately.
Very important for making fonts - ach glyph is a file of it's own
- Open them in illustrator and convert your glyph to an svg, either by using live trace or tracing it manually (recommended)
Notice that the glyphs must be a shape, not a stroke - otherwise the font will interpret the stroke as whatever fills it:
- Export each glyph as a separate svg - I recommend naming it as the glypoh it will end up being (a.svg, b.svg, etc., but this is not obligatory)
- Upload to any font producing website or software - I like Fontastic
