Miscalculation
A Little Back Shaping
Before I started what I'm posting here, I did a miniature 1/2 size version of this bag to see if the shaping would work the way I wanted it to. It did. I was happy. It took a little less than 1/2 skein of the main color. So I thought "cool! only one skein of each color". Word to the wise... doubling the width and height of a project does more than double the yarn required (area) for the project. I know this should have been obvious to me (Julie will be laughing now for reasons too detailed to explain here). Now it should be clear why I am a biologist and not a mathematician...
Anyway. The picture above is the the shaping on the long edge of the bag. The white lines were added by me to make the shaping clearer. This is about 2/3 of the way up. Try to imagine hemi-circular.
Side Shaping
There's also shaping to the sides, but it's more gradual than the shaping on the front and back.
And that's as far as I got before that lovely charcoal colored yarn ran out. So now I've got to track down another skein of Cascade 220 in 4002. Keep your fingers crossed for me that the ThreadBears have a skein of the stuff stashed away.
Good thing I have some other things to keep myself busy with while I wait.

Hmm..would that other project happen to be a BUCKET HAT?
Thanks so much for sharing your miscalculation. Now I feel better about all those flubs I've made myself :-)
UGH! The dreaded running-out-of-yarn. I wish you excellent yarn karma!
I love watching your felting projects unfold, can't wait to see the result. Good luck getting more yarn!
Not funny that you ran out of yarn, but it did make me chuckle for reasons you already know!
Well... a Bucket Hat is coming (I still haven't picked yarn)... but the next project I'll be putting up for show and tell is one that more or less mugged me in the yarn store and won't let me go.
