I was given a sewing machine about a couple of years ago until last year 2009 I've decided to do a refashion, which I did. I will talk about the refashion in another post, but after the refashion I just stopped using the sewing machine.
Why? It's probably because of the lack of skills, the cost of materials, or being creative. Although, I will be using most of the materials from my closet. I'm guessing it's just putting what I have now together.
I do know my way around the sewing machine. Thanks, to my home economics teacher way back in high school I've picked up a few skills. I really need to brush up on them, so check out the link above.
