The Sleeve Drape

 The sleeve block I used was from a size 8 dress bock. It fit very close to the dress form I was using, however my mannequin is a size 6 so that might have something to do with the extra few mm. I took these extra mm out in the under sleeve seam.

                                                                               **When sewing fine, satin fabric use a small (70) SHARP needle. This will help reduce snags in fabric. 

The sleeve block should have a front, back, elbow,  and shoulder notch.  Make sure all are very clear on fabric. Pin and sew dart.  Sew down under sleeve seam if you have sewn side seam.  You will then set in this sleeve by tunneling it through the arm hole,, RST, pinning as you match the notches and sew.

 If you have not sewn side seam you can pin the sleeve right sides together match the front, back and shoulder seams (shoulder seams must be sewn.) Sew sleeve to body, and then the sleeve closed with RST.

Of course if you cannot raise your arm you must add a little thing called a gusset. It is really easy to make! 

This is an image I found on my friend Google.

As you can see in the photo below I have sewn my gusset to my sleeve, now to be fair I added way to much in the height and regretted it.  Keep it olive shaped. 

Set into sleeve as normal, It should fit because it is a copy of that section of the pattern and should match. 

Like I said above, I had too much fabric in the gusset which caused for poor shaping.

Learn from my mistakes.
