eBay
It is not always possible to purchase short lengths of ribbon at a reasonable price, so I have usually bought long lengths, or assortments, to get the pieces I needed.
This has left me with ribbons I no longer want, so to clear them out I am offering them at a low start price and a low postage cost.
I have listed several different ribbons, along with other items, and will always combine postage; so simply wait for an invoice before paying.
