Well, not really, I just took my old one and made a little cover for it with the new more amore fabric from Stampin'Up.
It's good that it's removable because it means I can wash it if it gets grubby (and it probably will as it goes everywhere with me!) I just wrapped a piece of wadding round my filofax and used it as a template for the outside and inside fabrics. I quilted the top and hemmed one long side of the inside pieces, then sewed front and back together following the drawn lines on the wadding. Then I trimmed the wadding and clipped the corners, turned it right way out, and gave it a quick press before slipping it on to the filofax.
If you'd like a custom cover for your filofax or notebook, or to order some of this delicious fabric, please do get in touch...
