The first step to mending is admitting you have a problem. You may say "it's not so bad" and turn a blind eye on your growing problems. Without ever realizing how worn out and frayed you've become.
The next step is telling yourself that the mending project isn't too big! Once you see how really bad things have gotten you might be discouraged, but no matter how big every mending project starts with one stitch.
Next you start stitching things back together again. Start in a healthy place. The damaged area is too weak to start right in the middle of it, so start with a strong area on the margin and move in. The rest is one stitch at a time. Patience is key. A mending project may seem daunting and early results may not be encouraging but keep your end goals in mind and preserve.
The next step is knowing and accepting that mistakes will be made, adjust and move on. You will miss stitches and cross threads but don't dwell and press forward. For example, during my project by mending and strengthening the main trouble area weak points in other areas tore open. The frustration made me want to quit, but only doing part of the job would leave it just as weak if not more so. Despite my new set backs and realizing the project has more than doubled in size, progress is still only made one stitch at a time. With time and persistent you will have mended your problem.
For the last step, you will want to patch on a new panel over it and moving on. Your project's done, time to go out and have fun!
