I made bias tape and posted it in the destash thread and a few people asked how I did it especially since I did not use the fancy bias tape maker. So here you go!
start with a rectangle of fabric. Quilting cotton works wonderfully. This is a synthetic blend. It worked just fine. Orient the rectangle with the selvage closest to you. The bias is at a 45 degree angle to the selvage.
Fold one corner up to make a 45 degree angle. Press in place. Please note that I used a square of fabric. When using a rectangle, draw the corner up so that the selvage meets its parallel straight edge.
cut along the fold separating a triangle (on the left) with the rest of the rectangle (on the right).
without changing its orientation, move the left triangle to the end of the rectangle. Match the straight edges. The shape is a parallelogram.
stitch along the straight edge.
starting from the leftmost diagonal edge of the parallelogram mark the width of the strips for your bias tape. I used 2 tape measures and a straight edge to mark 2 inch wide strips. Measure strips 2 inches wide all the way from one diagonal edge to the other.
starting from the left mark the strips 1 - 2 - 3 etc. This is difficult to see in the photo so look close!
This is the part that is the most awkward. bring the selvage up to meet its parallel edge. Match the strips up but offset the strips by one number. Strip number one matches to strip number 2. Strip number 2 to number 3 and so on. there will be an unmatched corner on each side and the fabric will seem all twisted and wrong. Stitch the selvage and its parallel edge together making a tube.
Start cutting the strips. Cut strip number 1 off the tube. Ready for the cool part? When you get to the end of strip number 1 you're at the start of strip 2 so just keep cutting and the strips will spiral off the tube of fabric. This was not a perfect process and the lines did not match up perfectly. Do not despair. The finished product is still lovely and functional and you will be the only one to know the truth of the imperfect bias tape.
Now you have one long strip of fabric cut on the bias. Awesome.
March over to your ironing board and jam a needle through. leave about an inch of exposed needle.
Weave the fabric under the needle folding both raw edges over as you go. Use your iron to flatten out the rolled edges as you gently pull the fabric under the needle. You will have to do a little fiddling to keep the folds nice and even.
for double fold bias tape, once you have pressed all the raw edges to the center of your tape, fold the tape in half, adjust the pin and repeat the previous step.
press as you go.
roll it around some cardboard and you are done, my friend!
