You can note in the comments section of check out what bedding set you would like your custom sheet made to match OR design your own. For design your own you choose 3 fabrics for this sheet. The first is the fabric that will go around the outside of the sheet. The second is the piping(which is the small strip of fabric that separates the 2 fabrics). The third is the main fabric which is the part your baby will lay on, we suggest minky.
