Past Tense of Sew
The reviewed authorities give sew → sewed → sewn/sewed. Use “sewed” as the simple-past form. In participial constructions, both “sewn” and “sewed” are documented; this guide does not invent a regional or frequency ranking between them.
The simple past of “sew” is “sewed.” The past participle can be “sewn” or “sewed.”

Quick tests
Verb-form test
Is the sentence a simple-past clause rather than a participial construction?
If yes: Use “sewed.”
If no: If grammar requires a past participle, use the documented “sewn” or “sewed”; otherwise use the appropriate present form.
Caveat: The variation is in the past participle, not in the simple-past form.
Examples
She sewed the torn pocket yesterday.
“Sewed” is the simple past.
The label had been sewn inside the jacket.
“Sewn” is a past participle in a passive perfect construction.
They have sewed the pieces together already.
“Sewed” is also documented as a past participle.
Further guidance
Core difference
Use “sewed” for the simple past. Use either documented participle, “sewn” or “sewed,” where a past participle is required.
Fast Test
If the clause is a straightforward completed past action, choose “sewed”; after have/has/had or in passive constructions, “sewn” or “sewed” can fill the participle role.
Usage Boundary
Do not present “sewn” as the ordinary finite simple past, and do not claim one documented participle is regionally or statistically preferred without evidence.
