The ruler that came with the magnet is not a scant 1/4, for all you quilters.

I learned to sew using seam guides that screw into a little hole to the right of the throat plate. I found my various sized little metal guides very useful for sewing straight and also curved seams. Basically, you just hold the fabric gently and carefully along the guide. Sewing curves takes a little technique, but using a guide correctly really helps you get nice results. Not just by eyeballing it! I bought another sewing machine recently, a computerized Brother, that lacked a proper hole for using my trusted guides. The machine sews very well, but I have found it tricky sometimes to sew a measured allowance. For narrow seams you can use the width of the presser foot as appropriate. The machine manual has some settings and suggestions. The needle can be moved to various positions left to right. For someone used to old style mechanical machines, this new machine can be a little confusing or complicated at times! It still takes time to figure out exactly what the alignment should be for your chosen seam allowance. However, if you are sewing items with a 5/8" seam allowance, especially, here is where the Madam sew seam guide excels. The ruler can help you figure out exactly where to place your magnetic guide for your allowance. The magnet holds really well and does not damage your machine. Do be careful as you lower your needle into the little hole on the ruler, so as not to break or bend your needle! You will then see where to place the magnetic guide for the accurate seam allowance. The ruler has many seam allowance choices. I find the markings on the throat plate a bit awkward and short to use as visual guides, and these new machines have a lot of plastic. The top loading bobbin and its cover get in the way of longer seam line markings. And it still matters where your needle is positioned. Anyway, I have found that this little set is helpful.

I’m new to sewing. This helped me figure out my seam allowances very easily. Easy to use sturdy product. Love that it came with the seam magnet. Worth the money.

The media could not be loaded. I would pay this price for the ruler alone. It is a very handy 2 1/2“ x 5 1/2“ acrylic roller with needle hole placements for all of the commonly used seams in either quilting or garment making. However, I will not use the magnetic guide with my machine. The magnet is very strong, strong enough that it lifts the right edge of my throat plate. You can see in the photos that the quarter inch marking is to the left of the feed dog, So when the magnetic seam guide is affixed in the proper position, it is actually covering the right feed dog. The end result as you can see in the video is that the throat plate bobs up and down during sewing, and the fabric does not move through appropriately. If you are using a single hole throat plate while piecing quilt, there is a possibility that the throat plate would move enough to break your needle. If you want a nifty little ruler, this is a great buy. If you’re really looking for that seam guide, this is not it.
