I know that I started sewing when I was very young. I remember watching my grandmother sew at her machine when I was just 5 years old, and her letting me "help" her stitch a seam.
But the first real project that I remember completing under my own steam was an embroidery project. I had this bright yellow shirt made from India cotton. I visualized what it would look like embroidered, went out to purchase the embroidery floss, and then stitched simple, colorful flowers along the front placket. I was 10 years old.
I have definitely expanded my sewing repertoire since then, but when I look back, embroidery was what hooked me because I could see my project in my mind and then I created it. That feeling of accomplishment and success was what drove me to go to the next project and the next and the next. And I still have that shirt.
There is just something so alluring about embroidery. I recently embroidered a dress that I found on a sale rack with flowers very similar to those first flowers that I embroidered so many years ago. It's so easy to take some embroidery floss and transform an item from your wardrobe. I highly recommend it!
