For example I make pillows and add fabric buttons to them and most times the fabric button is a different pattern than the pillow. This makes me happy to create like this.
I also like to make fabric button magnets and create a three button gift set. Here I used some left over fabric from some men's shirts I had. Love the blue and white look of these and I thought they all looked good together.
I've also made magnetic boards and added fabric buttons to them as you can see below.
I buy my button supplies at cover buttons. My choice for sizes are the 1 1/2" size or it's actually called size #60. I've also purchased size #36 which is 7/8" but really my favorite size is the # 60
Cover buttons offers the buttons with or without the wire eye loop. As I never need the loop I buy without.
You'll need a template so you can cut your fabric to the correct size and not waste fabric.
Check out Cover Buttons link on how to use the assembly tool.
The magnets I use I get at Walmart. For me they are the most reasonably priced without having to pay for shipping costs. I use the 3/4" size and that fits perfectly for the size #36 and #60 buttons.
