#4 Yardage for Pillows, Duvet Covers
This #4 Invisible Zipper is the medium weight of Invisible zippers. The #4 means that the coil of the zipper is approximately 4mm across.
Other manufacturers call this a "#3 Invisible or Concealed Zipper".
I stock this medium weight invisible zipper as yardage in 90+ colors. You may purchase with the pulls on the tape & you just slide the pull down to the length of zipper you want before cutting it off the roll. Or you can put the pulls on yourself.
Why yardage & is it easy to use?
Having 5 or 10 yards of continuous zipper allows you to cut off what you need for your project with no waste. I sew the zipper tape onto my pillow, then add the pull. By adjusting where the pull is, you can match stripes on your pillow.
Videos above show you how easy it is to put the pulls on. Just don't forget to add "pulls" or "sliders" to your order.
My Invisible Zippers come in 3 weights: #2, #4, #6. Other manufacturers have #1, #2, #3, #5. Mine are a bit heavier in the #4 & #6. The number is the width of the closed zipper coil. Use the light weight or #2 in apparel, #4 in heavier fabrics like pillows or duvets & #6 in bridal (think tight bodice, multiple layers of fabric), heavier upholstery fabrics.
