There are several ways to sew on double-fold bias binding. The method described below is the one-step method where the raw edges of the quilted fabric are encased inside the folded bias binding which is then sewn in place. I chose to use this method because of the number of corners that need to be mitered. I find that pre-folding and pinning the corners works best for this type of project.
|Double-fold bias tape typically has one side that is slightly wider than the other side (I hope you can see this in the photo). You want to wrap the bias binding around the raw edge of the bun warmer with the longer edge on the wrong side of the project. This increases your chances of always catching the binding when sewing the binding on from the right side.|
|Leave a three inch tail of binding free and begin wrapping the bunwarmer with the binding near the middle of one of straight corner sections. Pin through all layers to hold the binding in place (if you can, insert your pins perpendicular to the edge of the bunwarmer instead of how the pin is shown here).|
|To fold a nice miter, when you approach a corner, hold the bias tape in place in the back with your finger right at the edge of the quilted fabric (do not pin within 2 inches of the corner).|
|While still holding the bias binding in place in the back, fold the binding over the corner as shown. The folded edge should be at a 45 degree angle from top left to bottom right. The binding will pop open slightly at the top edge and on the right side.|
|Wrap the binding around the right edge, about an inch from the corner and pin as shown. You can see how the corner is already starting to fold into the miter.|
|Press the right side of the binding down against the fabric all the up the the upper edge (see photo). The way the angle is folded is crucial to how nicely the miter folds and meets at the inside edge. Pin in place just through the top layers. Turn quilted fabric over and repeat this step on the back side and pin in place just through the bottom layers. Place both pins so that you can pull them easily when you are sewing. What I like about this method is that the front miter folds down from the top and the back miter folds in from the side. In other methods of wrapping and folding the miter, both miters fold down from the top creating extra bulk. In my method, the folds are opposite each other and this reduces the bulk at the corner, making it both more attractive and easier to sew.|
Continue pinning around the edge of the bunwarmer, folding and pinning the binding around the corners as you go. Pin more closely together in the curved areas to keep the binding from pulling away from the curve as you sew. Leave a three inch tail unpinned where you first began wrapping the binding.
|Once you have wrapped and pinned the binding in place, you can begin to sew it on. Begin sewing where you started pinning, leaving the three inch tail free for now. Sew close to the edge of the binding, removing pins as you approach them. |
As you approach the corner, slow down and pull the top and bottom pins out carefully just before you reach them. Stitch until you reach the fold and leave the needle down right in the fold. This step is very important to how the corners look on the back and front of the finished project.
Lift up the presser foot and turn the fabric in the machine until you can stitch in the other direction. Continue in this fashion until you approach the end of the bias tape. Stop stitching about six inches from where you began sewing.
|To nicely finish where the bias binding meets at the end, I like to sew the ends together rather than just folding and overlapping the ends which can be bulky. |
To do this, wrap each section of binding around the quilted fabric until they meet in the middle. Fold the edges of each one back until the folded edges meet each other. Mark on each piece the line where they meet. This will be where the seam will be sewn in the next step.
|Pull the ends of the bias binding around so that you can put the ends right side together with the seam lines matching (see photo). This can be a bit tricky because there isn't much room to manuever, but it can be done. Sew the seam and finger press it open. Refold the bias binding and wrap it around the quilted fabric as you would normally and pin. Finish sewing the binding in place.|
|Trim and loose threads and press lightly to set and flatten the binding. Admire!|
