Check out this great video on Whipstitching.
When hand stitching I've always have the tail of my thread on the out side of the project so when I saw this video and saw that the beginning tail and end thread tail were hidden inside of the pillow/project I was in awe.
I'm in the learning phase of soo many sewing related things. Even though I've sewn on and off for years; It's one of those things that you teach yourself and you do it the way you've always done it, but then you see someone else's tip or trick and you're like...like I said in awe.
It's a nice little video to view. Check it out.
