Here it is: A laptop sleeve from a leather jacket courtesy of Thread Banger.
What You Need:
- leather jacket with lining (or leather/other material + lining fabric, if you are not repurposing a jacket)
- quilt batting (I used Low-Loft crib-sized batting, and had quite a bit left over)
- 1 button
- black elastic cord
- marking chalk
- leather shears
- fabric scissors
- matching All Purpose thread
- sewing machine needle for leather
- sewing machine needle for wovens
- hand-sewing needle (not needed if your button is not shanked)
- leather/vinyl glue
Place laptop on your sleeve material, right side up, front edge facing away from you. Trace around laptop on all sides, adding 1''.
Lift and rotate laptop up on its back edge towards you, then wrong side up on top of the material. (Front edge will be facing towards you.) Keep drawing 1" around all edges. (I know this sounds somewhat confusing, so I included the diagram above to show how the material was measured.)
Cut the rectangle out of the material (cutting through both outer and lining if you are using a jacket), using leather shears. If you do not have a lining, place this rectangle on top of your lining material, trace around, and cut using fabric scissors.
Cut a small piece of leather about 1" square
Unroll batting from package, and leave it doubled up as you flatten it out. Place rectangle of material on top of the batting. Cut a piece of batting the same size as the lining, then trim batting about 1/2" on the sides only.
Fold material rectangle in half, and machine-stitch the edges together, using a needle for leather and upholstery thread. (Upholstery thread is not a must-have...but it is a lot stronger that regular cotton/poly mercenized, and is more suited to sewing leather and taking the stress of repeat usage. Also, f you have a walking foot or Teflon foot for your machine, it can help the leather from sticking.)
Clip corners and turn right side out.
Fold lining rectangle in half, and machine-stitch the edges together, using a needle for wovens and regular thread. This will make the lining into a "pouch." Do not turn right side out; the right side needs to remain on the inside.
Wrap batting around the outside of the lining pouch. Fold upper edges of lining pouch down and overlap batting piece at top edges. (Trim batting top edges if they are too bulky or long.)
Machine-stitch the lining edges down over the batting, at about a 3/8" hem.
Sew button to the material pouch you made in Step 6), about 2" down from the top edge on the front of the pouch.
Slide the lining into the material pouch, and slip the laptop inside to check for sizing. On the back side of the material pouch, tape one end of the elastic cord to the centre, about 2" down from the top edge.
Wrap elastic cord around button, and bring the other end to the back, cutting it and gluing it down next to the other end. Make sure the cord is taut around the button and will keep the laptop from falling out.
Trim the cord to meet the taped-down end.
Re-tape cords down with the ends free. Place a dab of glue under the ends and press them into it.
Remove tape and glue the small square over the ends of the cords.
Remove laptop and lining from the material pouch, and machine-sew the square over the elastic cord ends, first sewing a square around the edge, then an "X" shape in the centre.
Spread glue on the inside of the outer pouch, close to the top edge. Turn down top edge about 3/8"; clamp until dry.
Slip the lining back inside the outer pouch, pushing the corners all the way in.
Stitch around upper edge of laptop sleeve to secure the lining to the outer material, using a needle for leather and upholstery thread.
