Wire wrapping can be a very addictive hobby and even a very lucrative one too. Selling your creations online can more than pay for all your materials and it gives you a great sense of satisfaction too. Here is a pendant I made today for my daughter with an oval Agate gemstone, 1mm square wire and .8mm half round wire.
It did take about 2 hours but it was well worth the effort and my daughter loved it! I've only been wire wrapping for a few weeks but as you can see the results are impressive. Don't do as I did and waste money buying cheap tools as they are a waste of time. Get decent pliers etc from the start and they will serve you well.
There's a huge number of free sources online to teach you all about wire wrapping. You tube is a great place to start with video's like this one -
