Finding the center of a skein of yarn can be difficult. But following my method, you will always stitch from the center of your skein without any tension problems.
Step 1: Find the outside end of the yarn that the yarn company stuffed into one side of the skein. Pull that out and tuck it under the label or outer strands of the skein.
Step 2: Go back in one end of the yarn to the middle and grab some of the strands from the middle. Pull them out. See if you begin to get a bigger section of yarn. Basically, you want yarn barf to happen here. You want an inner blob of yarn to come out.
Step 3: After your inner blob comes out, make sure that only one strand of yarn is coming out of the skein. Follow the strand from the center of the skein to the outside of your blob. Start pulling the yarn off of the blob from the outside and lay it down. Reach to the outer strand of the blob and pull again. Keep pulling until you reach the end of the yarn which will be the center pull end.
Step 4: Start stitching from this end of the yarn. The working yarn should come loosely off of the top of your discard pile from unraveling that inner blob. When you’ve used all of the discard pile, the yarn should flow freely from the center of your skein.
