I also have the klutz glove for my grandchildren to use. My 14 yr old granddaughter know how to use the rotary cutter but know she has to wear the glove and have supervision but lets her do her whole project her self she also can run the long arm machine to quilt her quilts that she enters in show. 8 yr old grandson this summer got interested in sewing and cutting so I have a glove for him and let him try cutting on scraps to see how it worked. that satisfied him for now. 3 yr doesn't get to touch the cutter only blunt nose scissors and cuts threads for me.. I enjoy having them in my sewing room and it lets me sew while they are here and gets them involved.
