UPTTHOW Seam Allowance Ruler for Sewing Machine Trim Straight Line Hems 1/8" to 2", Perforated Seam Gauge with 15,30,45 Degree Line Indicators for Handmade Measuring Guide(1PC)

Great tool

Wasn’t sure if I needed this, since I usually use a piece of colored tape to make a seam line on my machine, but this works so well and is accurate and easy to use. No more trying to put a tape measure under my needle to measure the correct seam allowance!

Strong magnet, ruler is accurate. Everything is well made and a great value for the price

Bought this for my granddaughter who is learning to sew. This tool will give you the perfect seam allowance. Packaged well, arrived on time, easy to use and a great value. I would recommend this product regardless of how much experience you have at the sewing machine. It will last a lifetime.

I love it

Product met my expectations and seems fine. Have not used it yet.

Increased accuracy of seams made a whole lot of difference to the overall success of my quilting patchwork. Adjustment based on needle position is the key, & that position can be different between machines & between stitch patterns.

This has been a godsend for three eights inch seams. Before I was guesstimating because I do not have a gauge next to my sewing machine. This is awesome, it works exactly like described. You put your needle in the hole and mark the seam with the magnet. It’s easy to remove, but if you need it all the time it stays right there. It is genius. Arrived promptly from the manufacture.
