Got into creating my own gear, largely for backpacking purposes.
Started with a tarp with doors, which didn't turn out too bad, IMO. Inspired by Yama Mountain Gear, I added storm doors to both sides.
Speaking of which, the interior netting is the Yama Mountain Gear Bug Shelter.
I also took a stab at the Mountain Flyer from Bag Buff. This one I didn't do as great a job with, as I had some trouble with keeping material out of the way, meaning I did make some accidental stitches in the wrong places.
I've since also made a bike pannier and a daily gear backpack, I might put up a post about that later.
