My partner and I are getting married in Newcastle in a few weeks and then spending the night at Lumley Castle (can't wait!). We're only having a very small ceremony in the morning, then spending the rest of our wedding day and the following day doing a bit of chilled sightseeing (we don't live in Co Durham, but we know it fairly well as I lived here as a child). One of the things we'd like to do is head out to the coast, my usual favourite is by Marsden Rock as I went there a lot as a child, but I also have an idea that I'd like to collect some sea glass and then make it into jewellery when I get home, as a memento of our wedding weekend. I haven't been to Marsden for years and I can't remember whether there tends to be much sea glass washed up there. We'll definitely call at Marsden anyway, but would we be better heading to somewhere around Seaham as well? I know there's a lot of sea glass around there, but I'm not sure if it makes it further north. Thanks in advance for your advice.
