Vivilux sew-thru alignment stickers are the notion you will find so many uses for, you will ask yourself how you lived without them. The package contains 3 rolls of Alignment Stickers, 300 pieces in all. Designed by a sewist, the stickers are see-thru and work on both light and dark fabrics. The stickers have 45 degree angles printed on them. They have a low tack adhesive so they will not damage most fabrics and will not gum up your needle. After sewing, just carefully tear the sticker away. How do you use them? • Place the sticker at the starting and/or stopping point of a seam for accurate stitching. Great for Mariners Compass or other quilt block with multiple seam intersections. Set a sticker at a pivot point to make sure the piece stays the correct shape. • Place a sticker at a pivot point on a collar or cuff when topstitching to know exactly where to turn. If the angle is not correct, just mark the correct angle with a pen. • Overlap several stickers and use them to mark the placement of buttonholes. This will act as additional stabilizer. • Use the crosshair head of the 3-in-1 laser to find the center of an embroidery hoop placing a sticker at that point. • If you remove the sticker before stitching, it can be reused. Also, when working with a large hoop and stitching multiple designs, the stickers can mark the center of each design. • You will find more uses than this.
