I’ve just finished making the sleeve for my new laptop. I wanted a small slim sleeve to protect the laptop while it’s in another bag, so I intentionally didn’t include a handle or strap.
I made the sleeve out of heavy cotton fabric (actually leftover fabric from curtains that I shortened for a friend). I made a quilted lining out of a soft stretch knit fabric and batting. And yes, the stretch fabric was a mistake - I only picked it because of the colour, and it was so stretchy that it was very difficult to work with. I had to iron fusible interfacing onto the flap lining to make it stable enough to work with.
I used velcro to close the bag, and sewed a ribbon trim on the flap in a colour to match the lining. I had ideas for more embellishments, but I like it being clean and simple.
Ribbon detail from the flap. So pretty!
