Map your beds and their depths, separate composition from weave, match the fabric to each room's use, settle on a finish you can repeat, understand how bulk pricing and reordering work, and judge the supplier on service as much as stock. Do that, and your linen supplier becomes a quiet asset to the property rather than an annual headache.
If you are furnishing or replenishing rooms across a South African guesthouse or lodge, apply for hospitality pricing, build a quotation against your rooms, and keep every reorder on a single account.
