You could even just add the shapes to an existing bag if you have one. Make it as easy or complicated as you like.
First prepare the felt Tetris pieces
I made templates from card, 4x4cm squares, in the right shapes.
The ones like the L shape you only need to do once, as you can just flip the template to cut the ones that are the opposite way round.
These are the shapes and colours you need:
Unfortunately I don't seem to have photographed my pile of Tetris shaped pieces, sorry, you'll see them in just a second.
Next prepare the fabric bag pieces
I used the lining fabric to measure my outer fabric from the trouser legs.
Then I used the off cut pieces to make the handle pieces. As my fabric was limited I had to join shorter pieces to make the long handles I wanted. If you have more fabric you can just cut longer pieces all in one. Or you could have shorter handles!
So I ended up with 12 pieces:
- 2 x 41 x 44cm outer "trouser" fabric
- 2 x 41 x 44cm tea towel lining fabric
- 4 x outer fabric handle pieces 7 x 41cm (or cut 2 x 7 x 79cm if you have enough fabric)
- 4 x lining fabric handle pieces 7 x 41cm (or cut 2 x 7 x 79cm if you have enough fabric)
Attach the felt shapes
Before you make the bag you want to add the decoration to one of the large outer fabric pieces.
what can go wrong: If your felt needs ironing do it before you cut the shapes out, I did mine after and they pulled out of shape so I had to trim them again to make them fit - doh!
Play around with your pieces until you are happy with the arrangement, I was/am a Tetris fan so it was important to me that the pieces fitted like they would in the game. Remember if a line is all filled in it disappears (and you get points!) so you need to leave gaps on every line.
Once you you are happy pin them centrally to the bag front piece.
I attached each piece by stitching it on with a zig zag stitch, I wanted the thread colours to match so I stitched all the yellow, then all the green etc changing the threads as I went. It was a bit of a fiddle but worth it.
This is what the back looked like, I kind of like it!
I secured all the threads on the front by poking them all to the back with a needle, then tying them together in pairs.
Now make the bag
Once the decoration was on, I joined the 2 outer pieces and the 2 lining pieces, right sides together, pinning then sewing down the side, along the bottom then back up the other side.
Leave a 3 inch gap in the bottom edge of the lining fabric in the middle. This is important, you'll need this gap later.
Join the handle pieces you cut out earlier in pairs by stitching the short edges. If you had more fabric and were able to cut longer strips you won't need to do this.
Now your handles are ready you can position them on the bag. Pin them to the outer bag, one handle on the front and one on the back, right sides together. Mine were 6cm in from the edge.
Turn this outer bag inside out again and turn the lining bag right side out. Insert the lining bag into the outer bag so the right sides are together.
