I am very thrilled with my new quilting accessories bag....so far its holding everything i need to take to class.....the only thing is the back part that is suppose to hold the 18 by 24 cutting mat is about a 1/4 th of an inch to small....i really had to shove it in and its a little bowed....im praying it doesn't mess it up....that is the only reason i bought it....but....it is nice and sturdy and if you have a smaller mat you will be just fine
