I found the instructions very vague when it came to putting on an arm chair. NEED BETTER INSTRUCTIONS. It was totally opposite what they said to do. If you are covering an arm chair start at front and go over chair to back. Then seams will match up. The one little tag on the corner actually goes on the front left side when looking at your chair. Take a hint from the competing companies and tag each corner for placement as well as what direction you are looking at the chair. ie: front facing...

Found it difficult for awhile till I tried to do the opposite and then it worked. The video they sent me was for a sofa and did not help as it was opposite directions than what I had to do. For future use I personally labeled all my corners to remember how it went and did my own video!!
Covering also sheds small bits of fluff too.

I also contacted manufacturer and they were helpless and clueless.

Hope this helps
