Hence leather card sleeves came into being, for my shop anyway.
These alternatives to a bulky wallet are made of 100% genuine leather (minus the thread). For the outside I use 3 - 4 oz weight cow hide. The inside is lined with 1.5 - 2 oz pigskin for ease of sliding plastic cards in and out. The sleeve is completely hand sewn with strong, waxed linen thread using the saddle stitch. Not to be confused with a bookbinding saddle stitch (think; type of binding magazines/brochures would use), a saddle stitch in leather work is a two needle process which insures that even if a thread does break, it will not unravel as the thread around it holds it in place. This is much stronger than machine stitching.
Sleeves are available in both portrait/vertical or landscape/horizontal. I have also made a splattering of sleeves that favours all you lefties out there!
New sleeves to be added regularly!
