As a relative newcomer to the craft of sewing, I just recently started to realize the value of fabric scraps. That’s why I was intrigued when I heard of Looptworks, a new apparel company — started by three guys who worked together on product design and management at Adidas — that claims to make all their products out of excess materials. This MacBook laptop sleeve, for example, is made from scrap neoprene found in wetsuit factories in China and Thailand. I love the simple design; it also has two exterior pockets that fit a power adapter and a couple of thumb drives perfectly. Because their materials aren’t mass-produced, most of their designs are available for a limited time only. Looptworks rolls out new items every month on their web site and in selected specialty apparel stores in most major cities.
