A new and original idea by Jen Hogg, this silicone hemmer can flex in both directions. Use the holes to mark the position, pin the hemmer in place and press. It's perfect for shirt tails, necklines, skirt hems - anything curved. But pin it with a little tension to inhibit that curve and you can use it on straight hems too. Metric: 3cm wide, holes at 1cm and 2cm from either edge Inch: 1" wide, the holes are 1/4" and 5/8" from one side, or 3/8" and 3/4" from the other side. It's carefully designed for durability, with no rip points. The silicone is heat resistant up to 230°C. This has had an amazing reception from the sewing community worldwide.
