Looking after your linen is quite simple and straightforward. To make your linen last for long and remain in a perfect condition, you might find a following advice helpful.

Washing

Wash at 40º on a gentle cycle in your washing machine, using a neutral mild detergent or pure soap. It is not recommended to use chlorine bleach or detergents with whitening agents as they can weaken linen fibers and cause discolouration. Avoid overloading the washing machine as linen needs to be rinsed with plenty of water to remove all soap, detergent and residual soil, always!
White linen can be washed at 60º. It is possible to use oxygen-based bleach on white linen. 
Hand-wash will work fine for lightly soiled or delicate items but avoid scrubbing, wriggling or twisting as it can damage the fabric. 

Drying

Air-dry your linen whenever possible. It is environmentally friendly and will significantly reduce your electricity bill. Dry the linen garment by laying them flat on a terry towel or hang on a clothing line. Never leave in the machine long after the washing. 
When necessary, use a tumble dryer lightly and only on low heat setting using natural dryer balls which will help to soften your linen and cut down on drying time.
In general, always avoid over-drying your linen. If linen dries thoroughly, it becomes brittle and takes several hours to recover its natural moisture and full flexibility.

Ironing

It is best to iron your linen whilst still damp starting on the wrong side of the fabric, then on the right side to bring out the sheen, especially light-coloured linens. Iron dark linens on the wrong side only.
If your linen is entirely dry, it might be a good idea to use some linen water. These can be shop bought but there are plenty of online resources for simple homemade scented linen water. Our favourite is classic Mediterranean scented with lavender or verbena. 
However we believe that it is fine to skip ironing as slightly crinkled linen looks absolutely beautiful.
If there is embroidery on your linen garment, iron from the inside.

A note on using fabric softener

Linen naturally gets softer with every wash.
Although using fabric softener can be addictive, it covers fibers with waxy coating and overtime makes fabric less absorbent. It can also weaken linen fibers and cause discolouration of white fabric. After having been washed a few times, linen should feel soft and using softening agents should not be necessary.
