Quilting Difficulties

I have four of my own quilts sitting here waiting for me to quilt them.  I just did a twin and a baby quilt for one of my students.  I got one of my quilts called "Spinning Rails" on the frame and I was about half way done and my machine started acting up.  All of a sudden my machine is speeding up and slowing down and I have it plugged into a voltage stabilizer already.  
I noticed the stitches weren't right, so I stopped quilting.  I started to undo the stitching and at that point I only had to undo half a row, then I noticed the wrinkle in the back.  DARN IT!  I ended up spending all of yesterday undoing my quilting on two rows. 
I have blisters on both elbows that I didn't notice until I realized my elbow hurt and found the opened blister.  I now have bandaids on both elbows.
I will start again this morning after I feed the animals and clean the goat pen.  We had a great storm last night so I will clean really good today.  Easier to sweep up when the ground is wet. 
It poured around 1:30am and my first thought was: I'm not getting up and getting the clothes off the line, guess they will be rain fresh for real. :)
P.S. I want to make one of these sunglass cases or several.
