those who sew A) simple flat pocket onto the back and B) those who sew their pocket/sleeve making a "D" shape of their pocket with the flat side against the back and the curved/baggy side facing outwards. This latter method is meant to allow the rod to sit better in the sleeve and for the quilt to hang flatter.
Both of these are basically the same, the only difference being the size of lath you put into them.... Let me explain (or try to)
If you have a 4" wide sleeve on the back of your quilt and you ram a 3" x 1/2" lath through it, you'll have
A) a flat to the back sleeve
If you have a 4" wide sleeve and you put a 2" x 1/4" lath you'll have a B) a D shaped sleeve.
Some people make a D sleeve by
folding their sleeve fabric in two (WST) along the length of their fabric
and sewing 1/4" along the long fold with a large stitch,
they complete making the sleeve in the normal way,
lie it very flat to the back of the quilt and attach.
They then remove the line of large stitches and hey presto you have an amount of ease built in!
When I first exhibited at FOQ I stressed so much over the Attach a 4" sleeve to the back o your quilt instruction
I had, but it was a lil on the tight side .... do they use 4" laths??? Will they fit my sleeve??
There was no information out there about this! I really stressed ...
Now I can categorically tell you they use laths that are 2" wide by whatever it is deep ... so I could've saved myself so much worry!
Whether you chose to allow an amount of ease in your sleeve or lay it flat to the back of the quilt these are the steps to take to make a standard 4" wide Hanging Sleeve ...
1) Cut a rectangle of your backing fabric, width of your quilt x 9" wide.
2) Turn over both of the 9" edges by 1/2" twice and stitch down to make a neat hem
Your backing fabric should now measure ...... -2" width of your quilt x 9"
3) Fold your backing fabric, with the finished short edges Right Side up, in half along the length of the Rectangle, Wrong Sides Together
Your backing fabric should now measure ....... -2" width of your quilt x 4 1/2"
4) Sew along the Raw Edge of the rectangle using a 1/4" or 1/2" seam as you wish.
Your sleeve will now measure -2" width of quilt by 4 - 4 1/2"
5) Move the long seam into the middle of the sleeve and press open
6) Place the sleeve on the reverse of your quilt with the top edge just below the binding, the raw edged seam against back of quilt and centred in the middle of your quilt ... you should have about an 1" of space between the side edges of your quilt and the beginning of the sleeve.
7) Hand sew along the top of the sleeve, the bottom layer of the sides of the sleeve and along the bottom of the sleeve ... making sure your stitches do not show on the front of your quilt!
8 ) Run a 2" lath (cut to size, either a fraction smaller than the width of your quilt or longer, as you prefer) through the sleeve
Hang,
Stand Back and
Admire your work!
