My first finish of the year: another heavy duty car blanket for a big dog. This project started as the backing of Doggo 1, but I discovered that I only had enough to cover 2/3 of the back.
The Stash provided about 10 yards of a heavy duty denim that helped fill the gaps as well as serve as a backing. This was sewn around the outside (right sides together) then flipped right side out and top-stiched 1/2" from the edge. I added about 6 rows of stitching to secure the front and back (about every 6-8").
In addition to the leftover strips from old jeans, there are 2 upcycled wool jackets. I bought these at a second hand store for a different project for $1 each. At first I aimed to cut straight strips avoiding seams to get normal strips. I learned on a previous upcycle project that I quite like some of the original details left in. So often I'd sew down plackets or pocket flaps and include them.
While this is no masterpiece, it is a heavy-duty functional item as well as a dandy stash-burner for some other well intentioned old projects.
