I've never really had any bookends, I've seen decorative ones that I've liked sometimes but never gotten around to buying them. I either had enough books to fill the shelf that the sides of the shelf kept them upright or I just put the stockier books at the end of the row to hold them upright or used a heavy vase or something next to them. But a while ago I was having problems with the children's books, they are mostly hard covered and heavy and all different sizes and when they take one off the shelf the others all fall across so they can't put it away again so I decided it was time to buy some bookends. When I looked on Amazon they had packs of basic bookends for a relatively cheap price so I bought a pack of them,

I have no idea how I ever managed without them. I use one every few books, not just at the two ends. So now when they take a book out only a few can fall over and it's easy for them to put the book away again. The books are much neater and it feels so much safer because a big stack of books falling onto a child's hands could do some damage. But not only have I found them useful for the children but I used them for my books, then I realised that they could hold up my stacks of craft paper, separate my yarn on the shelf, hold my folds of fabric upright. Even when they are not needed for holding things up they still make a visual separator on the shelf. I wish I'd figured them out sooner.

And so I was wondering what useful things have others found that help with their crafting?
