I think Felt Tissue Case that I found on Martha Stewart is just adorable and can be made with the kids or for the kids. You can leave it plain as it is or apply some embellishments. The colors scream “SPRING”! Perfect as a favor for guests who are busy wiping runny noses when not attending showers. These felt cases hold travel packs and can be attached to a stroller or car seat with double-sided mounting tabs.
To make one, cut a 6 3/4-by-5 7/8-inch rectangle from felt, fold short ends in to meet at center, and pin. Sew sides shut with a 1/2-inch seam allowance, and trim with scallop or pinking shears; adhere mounting tab to back side.
