Just part of the process...

Yesterday I began designing the handlebar bag, and today I continued the process...

First I took the cardboard measurements and put them on pattern paper, adding 1cm of seam allowance to each side.





Next I used free fabric to make the first bag.  That way I can work out some of the kinks without ruining my good canvas...

I curved the lower corners because I cannot, for the life of me, figure out how to make square corners lie properly!  I think it looks nice with curved corners...

It was easy to sew up quickly on the machine...

And the final product looks ridiculous, but next time I'll remember to start sewing the sides on where I want them to start, just beneath the top flap...

Now I will mull everything over in my head for a while, and hopefully figure out the top flap, attachment system, and other small details....
