I do a lot of blanket stitching by hand around appliqué or sometimes pieced blocks. It looks to me like your stitches are too loose. I usually use 2 strands of embroidery floss and no hoop or stabilizers. Sometimes the stitches look a little wonky but as I go further along they get much better. I think the most important thing about doing the hand blanket stitching is to just get it as even as possible. But whatever works best for you. There is no law that I know of that dictates just how it must be done. LOL This will be a cute wall hanging. Here is picture of a wall hanging I did for my best friend for Christmas. I used 2 strands of floss around all the parts of the snowmen.
