Wash kitchen towels and napkins warm or cold and tumble dry low or air dry. Linen will become softer and less wrinkly with use. Over drying linen in a hot dryer causes wrinkles.
Linen and waxed canvas bags, purses, zip-kits, buckets:
Handwash gently in cold water. Hang bags to air dry / turn zip kits & buckets upside down to air dry. Don't allow water to pool on linen when drying or water rings will form. Happily, you will not want to iron the items made with waxed canvas because the heat will cause the wax to melt and stain the linen. Ironing is unnecessary anyway, because you can pat the linen flat when it is wet, before air drying.
