Here are my fixed elbows! I decided to go for the classic leather patch but with contrast thread to draw attention to the mend (and my bad bad stitching!). Such a feeling of accomplishment!
I used a Buttonhole stitch to sew left over leather i had laying around from when i was a student.
I love these old illustrations of stitching/sewing. My mum gave me a pocket Vogue sewing book from the late 1940’s a few years ago that i use all the time.
