Today I'm sharing a step by step series of photos to help you with your thread jointing.
When we want to make movable joints on a solid felted object we can't add any hardware like cotter pins or plastic joints, we have to 'sew' the parts together. But we need to do it in a way that allows them to be moved and posed.
When I do thread jointing I like to use dental floss, I've used it for about 20 years and still have my first ever bears. Floss is easy to tie and very strong.
Then, taking about 12 inches of floss (I measure it from my wrist to my elbow to save getting a ruler out) thread about 2 inches of the floss through the needle.
Take the needle INTO the inside of the leg, where it will touch the body, and out the other side.
Here you can see the floss going through the leg and the amount of thread left for tying off at the end. Just leave the end loose for now, about 2 inches or so long.
Next take the needle back into the leg NEXT TO where it came out. This creates a small stitch but it won't be noticeable.
Come out NEXT TO the tail end of thread on the other side.
