Fulling depends on extremes of temperature, from hot to cold, agitation by kneading and the use of laundry soap or soap flakes. Do not use detergent or washing powder. Dissolve the soap flakes in hot water and immerse one of the samples.
Start kneading the fabric without pulling, stretching or rubbing the knitting together. Remove the sample from the water frequently to check the fulling process. Rinse the soap out in cold water and pull the sample gently. If the stitches still move apart easily, continue the fulling. Keep up the temperature of the hot water. Stop when the fabric is dense and has a fuzzy appearance. Rinse the soap out and squeeze to remove excess water. Roll the sample up in a towel to soak up any remaining moisture and then lay it out flat, away from direct heat, to dry. Make a note of how long it took.
Try another sample but rinse it more often in cold water or knead it in hotter water.These things will make a difference to how quickly the sample fulls. Overwork one of the samples until it is matted and distorted to see the difference between correct fulling and matting. Keep notes of everything you do as you do it.
