I'm involved with the PTA at my boys' primary school, and every year we organize a Christmas Bazaar for the children. We make lots of little things, as cheaply as possible, because we sell them very cheap. It's just so the children can have fun buying lots of stuff and practice using money. Crocheting things is good because the small amounts of yarn I use cost practically nothing, but I wrack my brains thinking of simple but fun things to make that won't take too long.
Someone had donated some buttons, including lots of skull & bat ones, so I decided to incorporate those into bracelets and wristbands.
I made the bracelets using bobble stitches and with the bottons as closures, though I did one with a flower.
The wristbands are made with crochet ribbing and two colours of yarn, with the buttons hanging off the ends of yarn.
This is what they look like in action:
Making the bobble bracelets inspired me, as I thought they looked a bit like caterpillars, so I fiddled around a bit and came up with a way of making little worms and caterpillars.
Then I put them in matchboxes as little pets:
Finally, I made tiny little amigurumi of various creatures, snowmen and so on. Anything I could make with minimum sewing, so no limbs etc to add on.
The hedgehogs have bobble stitches for ears and fuzzy yarn mixed in for the spiky look.
The cats have popcorn stiches for ears and the tails are made as part of the body.
The snowmen are made from the top down so the hats are part of them, and the ends of the coloured yarn are pulled throught the top & knotted to make the fluffy bit at the top. The eyes and nose are French knots, with the yarn wrapped round the needle several times to make the nose stick out (I did the same for the birds' beaks).
This gives you an idea of the size:
As does this:
If anyone wants to know any more details about how any of these were made, just ask.
