|Supplied needed: purchased bias tape or homemade bias strips, yarn
Step 1: Center your yarn on the wrong side of your bias strip.
Step 2: Fold the strip over the yarn, match raw edges of strip
Step 3: Machine baste close to yarn, best to use a zipper foot if you have one.
Additional tip: stretch strip slightly as you sew to remove slack and to make piping smooth, trim seam allowance of piping to match seam allowance of garment.
Bonus step for knits: remove yarn after basting. It will make a flat piping that will stretch slightly, perfect for knits
