Trimming wooden venetian blinds??

[PuzzleRocks]

I have just bought Ikea wooden blinds for the whole house but most of the windows are not standard size. Is there somewhere I can take them to get them cut down to size?

I am in SW London.

TIA

We just cut our own down. Measured them and then cut them with a small saw, and carefully sanded the ends. Could you do the same? Failing that, employ a carpenter for a day to come and do the lot.

Thanks for replying.

I could, but i'm worried about botching. I might try on the spare slat.
