Which I have now done! So may I present the Fauxsoni Tote!
Details
Pattern: Felted Chevron Tote by Leslie Ann Bestor, from Interweave Crochet, Winter 2007. I do love a chevron. I do love Missoni. I do love a self-striping yarn. These three combined to make a match made in heaven! This is a very easy pattern - basically make a big piece of crochet chevron, sew it into a tube, crochet a base and sew it on (I think - I can't even remember whether it is sewn on or crocheted on!) and then felt it! Woo hoo!
And just in case you think to yourself, "but I have a front loader, I can't felt", well, take it from me, you can! I think I put a pair ofold jeans in with this to add a bit of friction, and did it on a full hot cycle, and it worked perfectly!

You can see in the before and after photos how much it shrank with the felting process. Just the right amount, fortunately. This is a very nice sized bag!

Yarn: The sadly discontinued Cleckheaton Vintage Hues. Sad because it is the perfect felting yarn. I used 7 x 50g balls of colour 1273 for the bag, but of course you could use fewer if you made the bag smaller, or used a different yarn for the base.
Hook: 7mm.
Time: 3 June 2009 - 25 October 2011. Really! I think I finished the bag and felted it sometime in late 2009 or early 2010. I really can't recall... And then I had a free afternoon last weekend so I dusted off the sewing machine (literally! Oh my was it covered in dust! Thank goodness it has a cover thingy), and sewed up a lining for it. With pockets even! Because I really dislike handbags without pockets for important things like your phone, purse and bus/train ticket! And pen, lip balm, keys and tissues. Um, I think I should have put in a few more pockets, heh!
Modifications: I think I made the pattern as written (I may have made it longer around), but I know I added a simple single crochet edging around the top of the bag. Just to ensure the edge was flat. I did plan to turn it over and make a seam, but that was an ill-thought out idea, as once it was felted it was too thick to even think about that! But not to worry, it is fine as is.
I am really happy with this bag! I love the colours and I love the way it has turned out! Finally! (Yes, another project for Binding Off 2011!)
