The tutorial continues!
SECOND, THE LINING
1. Cut out your fabric
There are only two panels for the lining, but they'll be a funny shape to match the outside. The easiest way to figure out that shape is to just trace around the outside of the bag, making sure to leave a seam allowance:
However, make sure that the top part that will be the lining next to the yoke is 33cm by 9cm (like the yoke), or you'll have trouble assembling the bag later.
Cut this first panel out, and then trace around it to make your second panel.
2. Add pockets as you like
There are a lot of great pocket tutorials here on Craftster; sushimifune's zippered-pocket tute, angelbum's slash pocket or the pocket instructions in gloriana's messenger bag tute.
3. Sew the lining together
Like you did with the outside, pin the two panels together with the wrong sides facing outwards. However, this time when you sew it, you need to leave a hole in the bottom that's big enough to turn the whole bag inside-out through.
4. Attach the closure
Plonk a magnetic clasp into the lining, or sew in some velcro, or do whatever else takes your fancy, and we're good to go.
THIRD, THE STRAP
Making the strap obviously isn't hard, but it's a bit annoying. Cut two strips of fabric as long and as wide as you want the strap to be. Mine were about 125cm by 6cm. Put them together right sides in and sew all along the long sides, and then turn your tube inside out (this is the slow and annoying bit; a chopstick or something might help the job along).
FOURTH, PUT IT ALL TOGETHER
This is the part that always confuses me. But I hope it's clear!
1. Put the strap in
First, the strap. I do not attach the strap the way most people seem to attach their straps; if you prefer the other method, that will work too. I sew the strap into the inside of the outside part of the bag before I put the lining in, so that I can see what's going on. Pin it in first like this; I put in about 8cm of strap:
From the other side, it will look like this (whoops, ignore my shoddy workmanship):
Now, important thing is to fold the top edge under before you sew it to the strap, like this:
I sew the strap into the bag with a rectangle with a cross in the middle, to make it as strong as possible:
2. Put the outside and the lining together
Put the outside of the bag inside the lining. The good sides should be together. That is, the good side of the outside is facing outwards, and the good side of the lining is facing inwards. The strap should be in between them (don't leave it sticking out, or your bag will explode!). Line up the top edges and pin them like this:
And then sew around most of that, but skip the area around the straps. That is, you'll leave a hole in each corner.
Turn the whole thing inside out through the hole you left in the bottom of the lining. You can sew up that hole now. Then push the lining into the bag. You're almost finished! It should look like this:
Fold the lining down against the straps like this and pin it:
Then sew all the way around the top edge of the bag like this (hopefully you will be better at sewing in a straight line than I am):
Sew in all 4 million lose threads... and it's done! Just remember to pin on all your emo badges or you won't be scene
I hope these instructions are easy to understand; feel free to ask for clarification or make suggestions if you like
