With Wikidata's 12th birthday coming up at the end of October, Wikimedia Deutschland is running a microgrant programme to support birthday events, with a deadline of this Sunday. Grants will be for 100 - 1000 Euros and details of how to apply etc are
here.
As you are hopefully aware, Wikimedia UK has a small
grants programme for volunteers, with project grants of up to £250. So you could apply to us instead OR use us as 'match funding' for the WMDE Wikidata birthday pot (which seems to be encouraged), particularly if a larger budget is required.
