A while back I ordered an advertised 15” laptop sleeve from Society6. Unfortunately, when it arrived it was far too small to fit my 15” laptop, which was odd…
The company told me that their 15” sleeves are actually only 14” (what the?!) and they gave me a refund but said to keep the product anyway (again, what?!).
To avoid material wastage, I deconstructed the original product to get the art print, added a wide boarder to get the extra inches needed and stitched everything up again over a new neoprene insert.
Not as sleek as a commercial product, but I think its rather swell and it protects my tech much better than the original!
