Interchangeable patches

This is not a full project but more of an idea that you can implement into a project.  A few posts ago I showed off my little embroidery that came with a cute bag kit.

It's OK but it's not 100% my style although the bag is cute.  Now I could make the bag without the embroidery or I could put it on anyway and deal but then I got thinking.  What if I could do both?

This is a bit of a 'make it up as you go along' job with the odd ebay purchase to help.  The first step was from the kit- make up the backing border.  This is pretty basic- two pieces of fabric cut to size (allowing for seam allowances) and then sew around the edges, right sides facing.  Then cut a hole in one side to allow you to turn it inside out to make a little pocket thing (this hole is going to be the back when it's attached to the bag).

This is the point where things take a turn.  Jumping on ebay, I found some very thin little powerful magnets- you can see one of them in the photo above.  They are about 1 mm thick but are strong enough to stick to a metal washer through a layer of material (I checked before sewing them in).

Handsew these into place inside the fabric pocket onto the BACK piece of material.  That way the front stays nice and plain.

This is the BACK view of the pocket- you can tell by the rough slit to gain access and the stitch marks holding those magnets into place

Then all you need to do is sew some metal washers onto the back of whatever pieces you want to add to the patch.

Not the most pretty sewing job but shhh, no one else is going to see this bit!

Put the top patch in place and the magnets will hold it in place nicely

With four magnets (plus I bought an extra just in case that I've just stuck in the pocket with the others to add a bit of oomph) it's more than enough to hold the patch in place- holding it up and giving a good shake doesn't move it so it should?  be enough to keep things in place.  At least for something with low interaction- it probably will not work as well as is on a piece of clothing that rubs and catches on other things.  You could boost the strength in the attachments if you used more magnets instead of washers to the embroidery- just make sure you don't sew the magnets the wrong way so they repel rather than attract!

Feel free to leave a comment if you try it!  I realise that I could also have used velcro, but this way you don't see anything if the embroidery isn't put into place.  Plus maaagneeets...
