Spackling is pretty much about covering your mistakes. Maybe you cut a hole in the wall in the wrong place. Perhaps you took three tries to hang a picture in the right place. Of maybe you just put your fist through the wall. Whatever the cause of the damage, you have probably already demonstrated the skills for proper repair.

Putting on the spackle in the first place is like frosting a cake. The putty knife and little trough used to mix and hold the spackle cannot be put away dirty. If you've ever washed something off with a hose, like dishes when you are camping, then this task won't be a problem for you. After the spackle dries you have to sand it smooth and see if you need a second coat. If you've ever managed a nail file, then this should be a cinch. Probably the hardest part is the waiting for it to dry when you'd rather just complete the job.

Repairing your mistakes is not necessarily difficult. You probably already have the skills to do it. But to do a good job, it does take time. Some things can't be rushed.
