I'd also hoped to do something with button embroidery on a steampunk theme but it was not a success. I used metallic threads and discovered they were a PIG to sew with. I could post a picture but I'm sure your imagination is more than capable of picturing a tangled, sparkly mess.
Would I recommend button embroidery to others? Yes, definitely. But not with metallic thread if you are a beginner!
It's an easy craft to suit people new to stitching and more experienced crafters alike. You can make big pieces if you want but it's also perfect for creating small card or scrapbook embellishments. Have an item of clothing or a plain bag you want to pep up with a button flower or two? Go for it! Have a spare couple of hours with a child who wants to make something and is old enough to be trusted with a needle? This is something you could easily to.
Tempted to have a go?
You will need:
Fabric to sew on to, preferably something with very little stretch
Embroidery hoop for keeping fabric taut while working on it
Notepad and pencil for scribbling down ideas and designs
