A Snap fastener consists of two parts – a socket side with a hole in the middle and a projecting side (with the ball) which fits into the socket as you join them together. They are attached to both sides of the opening and fastened by pressing them together, joining the two halves.
How to sew a snap
The ball side of the snap is placed on the back of the overlap side of the garment.
There are two types of snaps that you can use as a fastening. Other than the common snap that is sewn on the fabric, there are snaps that are the no-sew snaps like the magnetic snap.
You also get snap tapes with a line of snaps that you can sew on to your garment in one go.
The small snaps are used as a fastener only on non-straining areas but the magnetic snaps can be used on areas with stress. Magnetic snaps are usually used on bags and purses. The small snaps are used on loose tops, kid’s dresses
Whichever snap you are using, you should use interfacing on the back – this will reduce the stress on the fabric and prevent tearing.
The sew-in snap is easy to attach to fabric – you just have to sew the snaps on to the fabric with a hand sewing needle and thread. The holes on the sides of the snaps are for that – for you to make strong whip stitches through.
How to install a magnetic snap
What do you need to attach snaps ?
You can use snap fastener sets, a marking tool, a hammer, and a cutting mat or hard surface, if it is the no-sew snaps.The normal snap fasteners are not that much big or strong. But the magnetic snaps are not like that. They are bigger and really strong.
Your magnetic snap consists of 4 parts. 2 main parts which join together and two washers. The washer consists of a round disc with 2 slots through which the snap feet will be inserted on the wrong side.
