My favorite is the table top cutting mat I bought 100 yrs ago. They don't make them like this anymore...it's not self-healing. I don't care...it's BIG! I also love my scalpel type seam ripper.....I must love it, I use it all the time! I use a portable travel iron, too!!! Just started using it! It's much hotter than my iron....and DecoBond really DOES bond! (won't with my regular iron). I LOVE LOVE LOVE my 1/4" foot for my machine! WOW...I'm sewing almost like a professional!
The least liked is a small iron that someone gave me....looks like a regular iron but is only about 3" long. The cord comes out the left side....took me three attempts before I figured out it was for left-handed people. Also, the cord constantly falls out...!!!!
