I like them alot.
Much easier to use and when it takes so many pins to baste a quilt they sure save your fingers.
I also like the clips that you use to hold fabric on your cutting table. Since I cannot get down on the floor I have to baste my quilts on my cutting table and this requires moving the quilt in order to baste it all.
These clips are not bulky like the black office clips that take strengh to open.
