Alexander Olch offers a solid variety of fabric options that include cotton, linen, wool, and tweed. The patterns are plentiful as well, with bold checks and subtle stripes amongst the selections. Manufactured here in the U.S.A., these nifty rounds clock in at approximately 10.5 to 11 inches in diameter. Olch rounds can be purchased from their website, or with other vendors such as Mr Porter or Barneys New York. Retails for approximately $60.00 per round – unless you are fortunate to grab a sale.
