blanket stitched triangle quilt
I recently found a half finished quilt made of fabric squares folding in half to make a triange...batting is put in and then it is sewn on all three sides with a blanket stitch using what appears to be crochet thread. The triangles are then joined together to make a quilt with the same thread. No pattern was with this and I was hoping someone would have one. This was originally done by my mother-in-law who passed 21 years ago and I found it in my sisters attic after she passed this spring so it has become important for me to finish it. Any help would be really appreciated. I also am having trouble finding the crochet thread its thinner then size 3 and I cant find a match. I am going to try emailing or writing thread companies and see what I can come up with. All the fabric was stored in a bag with the half made quilt so I just am looking for the pattern and the thread.
