Wonder Clips

 

What is it? - Wonder Clips are perhaps the most versatile and useful sewing tool ever devised.  For years sewers have used binder clips, hair pins or even clothes pins for any number of sewing applications where an alternative to pins is desired.  The Wonder Clip, designed and manufactured by Clover, is the first clip developed specifically for the needs of today's sewers, quilters, crafters and beaders.  The Wonder Clip is available in two sizes.  The Original Wonder Clip is 3/8" wide and 1" long.  The base is flat to allow it to lay smoothly on any level surface like tables or sewing machine needle plates.  The base is also marked in 1/8" increments to ensure accurate and uniform application.  The Jumbo Wonder Clip is 2 1/4" long with 1/4" increments marked on the base.  They are sturdy, don't leave marks and are easy to see through to enable accurate positioning on  your projects.  Original Wonder Clips are available in packs of 10, 50 or 100. Jumbo Wonder Clips are available in packs of 12 or 24.

 

What does it do? - We are still counting!  We'll let you know when people stop finding new uses. Sewing - Wonder Clips are a natural for holding together layered sections of fabric during the sewing process.  Quilt bindings, hems, piping, seams, etc., all can be held securely in place while sewing.  Unlike pins, Wonder Clips do not leave holes in leather, delicate or vinyl/laminate type fabrics.  You can easily position appliqué or hold patterns in place while marking or cutting and avoid puckering issues caused by using pins on some fabrics.  Knitting and Crochet - Wonder Clips are a real boon to knitters who are always joining their work at seams . . . side seams, sleeve insertion, sleeve seams etc.  For those who crochet life just got a whole lot easier too.  Clip all of your intermediate sections together in organized groups until you are ready to join them and then use the Wonder Clips to hold sections together while you attach.  If you are beading with your crochet the Wonder Clip can be used to position the beads away from your work until they are needed. Crafts and Beading - Wonder Clips are like having a "third hand".  They are strong enough to hold virtually any sewing, art, or general craft materials in position while you glue, sew, paint, tie, staple, embellish, dry, or carve . . . whatever is required to create your masterpiece.
