Making a facing/binding exactly the right length for an opening
Eager to get them attached, I didn’t do any adjustments to the fit of the sleeves so the pleats as marked on the pattern didn’t translate very well to my garment and hung oddly (totally my bad), so I unpicked them and pinned the folds again to make them look better. I found this very fiddly and used a combination of another person and a lot of trial and error, pinning and repinning.
The instructions then direct you to sew the facing into a circle first, then attach it to the sleeve. In changing the pleats, I suspected the sleeve opening may be a slightly different circumference now to the original pattern, and therefore not match the sleeve facings. To guard against any mismatch, I did the following:
(The photos below were set up for demonstration on the finished garment and so there is no raw edge to the sleeve and the original facing is attached)
Tip: Making a facing/binding exactly the right length for an opening
This technique can be applied to many situations such as a neckline or armscye, wherever you are attaching a strip of fabric or binding to a circular opening. I like the additional accuracy of this technique compared to just measuring.
Step 1: Pin the facing / binding to the opening, before sewing it into a circle
Lay your facing on the sleeve, right sides together and raw edges level. Place the first pin at the underarm seam leaving your seam allowance free, in this case 1.5cm.
Continue pinning all the way round until the facing overlaps again.
(As noted above, photos were taken on the finished garment, hence the original finished facing is visible on the inside of the sleeve)
Step 2: Mark where the overlap is on both ends
This will indicate where you need to sew the seam to close the facing / binding. In my case the facing was too long, in which case carry on as below. If it is too short you need to cut another longer piece and then continue.
Mark the overlapping piece of facing level with the underarm seam and then join the line. I used a Prym Aqua Trick Marker which just needs a dab of water to remove the mark.
Then mark the other end of the facing underneath in the same way.
Step 3: Pin the facing together along the line
You can remove the entire facing to sew the seam if you find this easier, but this way just saves repinning again when sewing the facing to the sleeve. Remove enough pins to allow you to put the two ends of the facing right sides together, pinning along the marked lines ensuring the pin pierces through the lines on both sides.
Step 4: (Optional) Glue the seam allowance together to help hold it in position
Since the next stage is now to sew along the pinned line and therefore having to remove the pin, I used a Sewline Fabric Glue Pen on the seam allowance. I knew I would be trimming this part, so it just helped hold it together whilst sewing. You could also use pins away from the line or nothing at all and just hold it together with your fingers if you can hold it accurately enough.
Step 5: Sew the seam of the facing
Sew along the marked line, removing enough pins to allow you to fit it under the presser foot comfortably without catching the sleeve.
Step 6: Trim the seam allowance and pin back this section to the sleeve
Trim the seam allowance and pin the loose section back to the sleeve. You can now continue with sewing the facing to the sleeve knowing you won’t be left with a flappy bit at the end!
