LIMITED EDITION Blue Crabs print Rectangular Acrylic thread drops for your floss storage or temporary WIP needs. 10 rectangular acrylic thread drops & one 1.5" loose leaf clamp/ring per set. Each thread drop is made from 1/8" Ink on acrylic & can be written on using a Sharpie to label your thread color &/or symbol for easy matching to a cross stitch pattern. Recommend only writing on the non-pattern side of the thread drop to preserve the longevity of the image. All thread drops can be washed using soap & water. The easiest way to remove sharpie is by using isopropyl alcohol. Isopropyl alcohol will not hurt the acrylic. Other harsh chemicals may mar or melt the acrylic & are not recommended for use. No guarantee against any non-recommend cleaners or chemicals. Due to the nature of the pattern on the acrylic I do not guarantee consistency in pattern nor against minor imperfections. Rectangular thread drops measure approx 48mm long & 28mm wide. The large hole for the floss measures approx 17mm & the smaller hole for the ring is approx 7mm. You will receive 10 random patterned thread drops & 1 ring per set. Limited Edition Rectangular Blue Crabs Print On Clear Acrylic Thread Drops. A Crossed in Stitches Exclusive
