This step is optional, you could just use a piece of ribbon around you outer cover to keep it closed.
Warning! the next step involved cutting your embossing folder in half!
If you want to make a belly band, using a contrasting card stock (I used 300gsm double sided pearlescent card), cut to width suitable for a border embossing folder of your choice and long enough to wrap completely around your outer cover with a small overlap.
I used a Tattered Lace Rose embossing folder.
My embossing folder had it’s hinge at one end which meant I could not do a continuous strip longer than the folder. I cut mine at the hinge, placed the 2 sections together and then sellotaped them together down one of the long edges. This allowed me to emboss the entire length of the strip.
My embossing folder looks a little worse for wear now after doing a large number, but it still works fine.
