Buttonholes

Make a sample sheet of buttonholes in different sizes to save time testing to get the right size buttonhole. Use a fairly average weight fabric and stabilizer. That way you can be pretty accurate.

If you are using a computerized sewing machine that allows you to key in the size of the buttonhole you can even jot down the size in mm next to each buttonhole so then after slipping the button into the sample buttonholes you can then just dial up the right size - say 20mm and off you go!

If you are using a manual sewing machine you can also use the method above and transfer the best buttonhole size on to your test fabric.

Always do a final test buttonhole on a scrap of the current project fabric as well as the stabilizer your using to allow for different weight and weave in fabrics.
