It's a finish

Yellow fabric

Black fabric

Retro tea towel

 The tea towel had only enough fabric for the front and back

with a tiny bit left over

so the sides and bottom I made in plain black

 The yellow I used for the inner bag

With a pretty pocket on the back

 The handles were just two strips of material

one black and a thinner yellow

 Inside I made a huge pocket for my file and book

plus a pencil pocket

 Tea bags fit in pocket

plenty of room in middle for everything else

 The straps are long enough to be a shoulder bag

 Another tea towel, with material from my stash

next project ?

Two things dictated the size of this bag, my A4 file and the size of the tea towel, I only had one, purchased in a pack of ten for £5.99, with fabric from my stash, and coloured threads I already had.
I cut the retro patterned tea towel first, making it as long as I could, two pieces for the front and back, I then cut 2 yellow pieces the same size.
I cut 1 black and 1 yellow long wide band for the sides and bottom.
I cut another black and yellow long thin band for the handles. I folded the sides together and ironed each band and then pinned the yellow on top of the black, stitching with yellow thread on the top and black underneath. I would have preferred to had the retro fabric for handles, but I did not want to buy another pack of tea towels for for 1 piece of material.
I then added the pockets to the yellow inner, the big pocket for my folder goes to the bottom of the bag.
Next I stitched the black sides to the front and back of the bag. I then stitched the bottom, making the outer. Then I made the yellow inner in the same way.
I pinned the handles to the outer, measuring to ensure they were central, I placed the inner inside folded the top and stitched both bags together. I prefer to make a bag with an inner, it's much neater inside and the second fabric gives the bag loads of extra strength.
I really enjoy making these simple bags, it was a fun afternoon, and now I have everything together for my next class.
My daughter tells me yellow is in this year, plus retro, so for once I'm on trend.
