Actually, this project was on the top of my holidays sewing list but I have just finished it now. Using one tutorial from Sew4Home, as suggested by my friend, I found that this bag was quite easy to make. Basically, it was just an usual tote bag but the straps were using cotton webbing. I received my cotton webbing yesterday from Ma Petite Mercerie so I could finish the bag this morning.
Now, my yoga mat has a home... :D
