Hi Cheshire~Rose,
I saw your post earlier and followed your link and then spent ages exploring the Chesterfield Canal Trust website, reading all about the restoration work. When I first read your post I though that the trust might be doing a little clearing of a slightly over grown waterway, but not so, this is a massive project and it has been fascinating woking my way through the photo journal on the CCT site.
You say that donations can be sent with a CWDF reference, will a note sent with the postal order cover that?
Good luck with this.
Tumsh.
