We have 6 simple steps for how to unshrink linen. First, add a gentle soap to lukewarm water. Next, allow your linen to soak for 30 minutes. Third, gently remove the linen clothes from the soak. Then, roll your clothing inside a towel to squeeze out excess water. Your clothing should be damp instead of wet. Next, lay your clothing out on a clean dry towel, carefully pulling the fibres back to their original, pre-shrinking size. Finally, allow your clothes to air dry.
