Can I run the linen apron in the washing machine with other laundry?

It can be put in water, but it must be put in alone. The washing instruction for this apron is separate water wash^[1]. While this means there is no need to send it for dry cleaning, it is also a condition not to put it in the same tub with other clothes.

The reason this condition is attached comes from the material. This apron is a LINEN 100% product made with linen fabric woven from high-grade Northern European flax yarn^[2][3]. Generally, when linen gets wet, the fibers swell and become vulnerable to friction, and if it bumps against other clothes inside the washing machine tub, fine wrinkles can easily form on the surface or the texture can become rough. There is also a possibility of color bleeding if washed together with dark-colored clothes, so it is safer to wash it separately, especially for the first wash. A common method is to run it on a gentle cycle in lukewarm water, keep the spin cycle short, and then smooth out the texture by hand while wet before hanging it to dry.

The thickness is medium, there is no elasticity, and the size is one size (free size)^[4]. Because fabrics without stretch easily retain marks if wrung out by twisting, it is better to press the water out rather than wring it.

hmmm, an apron is an item worn on the premise that things will get on it in the first place. In that you can wash out that day's splattered stains right that evening, even with the condition of washing separately, the very fact that it is water-washable is the condition that lets you take out and use this single piece often.
