This patented system features a lightweight, hand-held tool thatís reliable and easy to use, with a durable metal-feed mechanism. Its micro fasteners are better than thread, metal staples or pins, and hold fast and tight.
With the marketís smallest needle and smallest tacks, MicroStitch is also gentle on fabric. The tiny, versatile fasteners apply easily, can be sewn over and removed with a quick pull or snip. For quilters, it makes the basting process faster and easier, with tacks that are 35% smaller than other options.
(A tip to getting more hits in search for things relating to retail fabrics and joining them is to use "quilt" in the search, reflecting the popularity of that creative outlet that has not much in common TQs and UQs discussed here. Sewing shops? Nah: Quilting shops.)
