Attach one static variant
Choose a file such as Family-Regular.ttf rather than a variable font or an entire collection. Each weight and style should be treated as a separate project until family workflows are supported.
Preserve structure, replace outlines
Safe editing keeps glyph count, order, IDs, substitutions, positioning, components, and untouched tables stable. A changed outline remains assigned to the original glyph ID.
Unchanged glyphs remain available
You do not need to redraw the whole font. Font Studio stores changed glyphs and falls back to the original template for every glyph you leave untouched.
