The cover will arrive with the elastic already sized to fit your board--just put the cover on your board and you are good to go trust me, you'll love it. And if you want an even snugger fit on your board, simply remove the cover, tighten the elastic drawstring, tie a new knot, and replace it on your board. Measure the board from top to bottom and from side to side. Do not measure the actual size of your current cover; i will make your cover large enough to wrap around and beneath your ironing board.Please select carefully and measure your board if in any doubt about ordering the correct size. I'm also happy to send you a snippet of fabric if you'd like to see the colors in person. Spot clean or hand wash only. Although the fabrics i use are color fast, very infrequently the bright and solid colors can run. If that is a concern with your item, i recommend that you set the colors before use. You can find many different instructions for setting colors in fabrics on the web. If your cover is padded, please set the color by hand rather than using a washing machine. Convo me if you would like to special order a board cover in the colors/fabric and/or size of your choice. Is it time to replace your worn out old ironing board cover with a fresh new one are you having trouble finding just the right print to match your decor is your board an unusual, hard-to-fit size. No worries i've got you covered. This cover comes with its own padding sewn right in made with a double thick layer of cotton batting, the padding provides the perfect surface for ironing. If you prefer a separate pad and cover, i sell those too. Or you can provide me with 1- yards of your own 100% cotton fabric for a truly custom cover. This item is made of 100 percent cotton fabric and thread, bias tape, elastic cord, cotton batting.
