Swimmers 11 and up will tie-dye at 7:00 (before their practice) and swimmers 10 and under will tie-dye at 7:45 (after their practice). Items to be tie-dyed should be 100% cotton. Please prewash your items and bring them damp on the 10th. You will also need a large Ziploc bag to carry your tie-dyed items home in.
