They say mistakes is the step to new inventions. I like the wider trim and would be perfect to personalize with name, initials or a small design especially if you have the embroidery machine.
Men like these also to carry in their pocket so I made some with masculine fabric, sports fabric, college fabric for students etc. We sold them at our church bazaar with a pack of tissues included for $2.00.
I have also made these using suede fabric with braid along the opening edges and they do not need any lining. You just cut 1 piece of suede 5 1/2 inches by 7 inches, sew a piece of braid trim along the 5 1/2 inch edges. fold to middle and sew across ends. Since it won't ravel, no need to zig-zag. Turn right side out. You could add decorative stitch along opening edges instead of braid. Either way they are more luxurious so we sold these for $4.00 with pack of tissues included.
