*The Wonder Clips are made of a hard durable plastic with a strong metal spring.
*Each Wonder Clip opens up widely - up to ½ inch, enabling several layers of material to be held firmly together.
*The foot of the clip has two lines allowing you to regulate seam depth and as the foot is flat, feeding up to the presser foot is not a problem.
* The clips are also very easily moved.
*The damage caused to delicate fabrics (and occasionally to fingers and feet) will be a thing of the past.
* Apart from their obvious use in sewing, quilting, crocheting and beading they are useful in many other ways - holding papers together and for those working with marquetry, you will be happy to hear that the clips are strong enough to hold sheets of veneer together and help with model building.
* For those of us whose eyesight is not of the best and finding straight pins in fabric can be something of a challenge, the clips solve another problem.
* In the unlikely event that you are not happy with the clips, there is of course a full money back guarantee .
