I used fabric scraps that had small prints. It was tricky to get the fabric to sit in the exact position I wanted it to, but I got better the more buttons I made.
Button covering kits are available at craft stores, but you will find a larger range of sizes online, particularly on etsy. You can buy buttons with a stem to sew onto garments, or flat backed buttons to glue on jewellery findings like earring posts. For the hair clips I've used flat backs. The best glue to use is E-6000, which is a jewellery grade glue.
Hair clip stems are available for great prices at an etsy shop called Skull Buttonry, where all the profits go to Cate Bolt's Foundation 18. Buy crafty items and give money to charity at the same time - YES!
I also made some very cute Little Red Riding Hood hair clips but they have been wrapped up and posted off as a surprise gift for someone who will hopefully get them today!
Now I just have to decide which of these three pairs I will include as part of a birthday gift for one of Anna's little friends who is having a birthday party this weekend. Which are your favourites?
