This is one of the best notions in my opinion. Just sew it on at the last phase of your project.
My problem with traditional magnetic closures is to decide where it need to be installed. Also, I have to make a hope in fabric to install a metal place prior to constructing a bag. It is a lot of procedure to take. Then, I met this Sew-on Magnetic Closure about 5 years ago. All the bags I design and which requires a closure recommend using this. A friend of mine is a knitter who always wanted to find a way to close her knitted bag. Now she is happy to find out that she can just sew this one on to her projects.
Made in Japan and imported.
I used a strong color of thread here in order to show you how to install, but you can use a color of thread that can be blended in with the color of the closure. Sew-on Magnetic Closure AK-25-14 comes with 4 different colors: Gold, Silver, Black nickel and Antique gold.
