The most common reasons that extra stitches occur are either accidental yarn overs and inadvertent knitting into space between stitches. … Then, when you go to knit the next stitch, the working yarn goes up and over your needle creating an extra loop on your needle as it makes that next stitch.
Why does my knitting get wider?
If your knitting is getting wider, it means that you are adding extra stitches or changing your tension along the way. More and/or wider stitches create the extra width. To prevent this, ensure that you are not making any new stitches unless the pattern tells you to.
Why does my knitting look bad?
Cause: You may not be holding the tension of your working yarn consistently. Some stitches will be loose and some will be tight, causing your knitted fabric to look uneven. Solution: If you are new to knitting, this is a common problem that will improve with practice.
What if my knitting gauge is too small?
If you have MORE stitches per inch than your pattern calls for (see diagram to the left), your stitches are TOO SMALL. Try a LARGER NEEDLE. If you have FEWER stitches per inch than your pattern calls for (see diagram to the left), your stitches are TOO LARGE. Try a SMALLER NEEDLE.
