Here's a silly question just because I'm feeling trivial today.
I'd simply like to know, what do you use as a bookmark?
I'm a particularly hopeless case because people often give me beautiful bookmarks.
Chet gave me a wonderful "book bungee" like the ones above which also keeps the pages of the book together in my bag.
Anna the Russian Poet/Princess gave me a couple of delightful "book thongs", which are not only dead pretty but sit between the pages without slipping out.
But somehow they never happen to be around when I need to mark my page, and I end up using all kinds of things, bits of torn off newspaper, serviettes, receipts, queue numbers, sweetie wrappers, and ringgit notes to keep my place! I often pick up advertising cards, especially those for arts events, and leave them between the pages when I finish the book as a kind of postcard to posterity. I've even been known to use a sandwich on occasion, but honestly wouldn't recommend it. (Too much DNA on the pages.)
But I would never, never, fold down the corner of a page. My dad used to do that with library books all the time, and it drove me mad!
I've come across some good bookmarks in second-hand books. Once I found a £10 in a novel and used it to buy Adam Ant's Kings of the Wild Frontier album (which shows how long ago it was!), and then there was a fascinating old letter in a Victorian novel.
I like it when bookshops give you a nicely designed bookmark as a freebie with your purchase. Only Silverfish does this here, I think, which is one lost marketing opportunity. But some of the UK and US bookshops have really nicely designed ones that you want to keep.
Bookmarks have a history as long as the book, and some have become collector's items.
Meanwhile, if you feel at a bit of a loose end today, why not have a go at making this rather splendid origami bookmark?
