I am 66 years old.I always knew about a needle threader,but could not figure out how to use it. ( My mother was a seamtress but passed away June/2011 ) I guess I never did ask her how to use it OR, I never needed to, as my eyes were still good.Now they are not so good, thus ,explains why I have a hard time to thread the needle.So I going to sew up a quilt for my 4 year old grandson,this morning & guess what? NO,I could no NOT thread the needle.So I decided to google it.I found it on: ifixit.com Excellent! Finally!! No,I am on that great on the computer yet.But,I am learning.
