Petal / Tulip sleeve can add a beautiful touch of whimsy to any design and really make an outfit standout. Now I’m going to show…how to make a tulip sleeve from basic sleeve pattern. We can make this in two methods.
Cut your fabric by using the paper draft. Now you have 2pieces of each right side sleeve and left side sleeve. Measure the curved hemline of each piece. If the measurement is 10” cut 2 bias stripes of matching or contrast color fabric with 10” length & 3” width (hemline stripe width depends on your wish).
Fold the bias stripes half in lengthwise by facing wrong sides together and place it on the hem line at wrong side and sew with ¼” seam allowance. Do it again for the other piece.
5 Turn the stripes to the right side of sleeve pieces and press. Now give top stitch to fix the border in hem line.
Time to form this Tulip Sleeve as a basic sleeve to attach with armhole of dress. You have to overlap each other pieces to form tulip shape (make sure mark of C has to be in the same point, which should be stitched at shoulder line). Give temporary stitch to fix the two pieces together. Now you can sew this Tulip sleeve at the armhole of dress or shirt like usual sleeve attaching method.
Mark sleeve pattern in paper by using the first method’s step 1 with simple addition of 1cm extra at the side seam of each side.
Join to fix the Excess 1cm portion on side seams of each piece with glue.
3. Now you get the single piece of sleeve. Cut the fabric with this paper draft.
Finish hem lines with bias stripes. Sleeves are ready to fix with the dress, but in this method the sleeve can fix after finishing side seams of dress. The mark A mentioned in the above image is to be stitched at the underarm seam and the two marks of C have to be placed at the shoulder line.
