Cut your quilted fabric to 26" x 38"
Bind around edges of quilted fabric piece, when the binding, add two loops opposite each other along the long sides of the tote near one end (see image of open tote above)
When placing the button loops, be careful of placement. You want to be able to fold fabric over your 18" x 24" OLFA mat, and when buttoned closed you don't want your mat to slide out of the sides of the tote.
Lay belting on the fabric to create an oval shape - this will create the handles of your tote
Securely stitch belting to the quilted fabric
To make pockets, lay out all the OLFA rulers you want to carry in your tote - this will help you determine placement of your pockets.
Cut a piece of fabric so that when it is folded in half, it will be twice as big as the ruler plus one inch all the way around the ruler.
Fold the fabric in half and sew the two ends, using a 1/4" seam allowance. The top of the pocket will have a double raw edge - I added binding to the top edge, this will give the opening extra strength as well as a decorative edge.
Make as many differently-sized pockets as you want, then stitch the pockets to the quilted cover. Stitch down along three sides - leaving the top edge (with the binding) open.
When stitching down the pockets - keep in mind that your tote will have two top edges (the tote will fold in half when you carry it - so position pocket openings so they face up when you close the tote.
Fold tote closed, and mark the spot you need to place your buttons. Stitch buttons in place.
You can stow many different OLFA rulers in this tote - consider the following:
Shaped rulers like the 6.5" Triangle or the 6.5" x 6.5" Square Ruler
Large rulers like 12.5" x 12.5" or 16.5" x 16.5" square rulers
You can also stow your OLFA rotary cutter in deeper pockets.
Don't forget - your mat can fit into the tote itself without a pocket!
Consider adding a stuffed pillow to use as a pin cushion - this can be put into a pocket or you can add a ribbon to tie it to the tote handle.
