tina has about 6 of 7 standard styles of bags, and does variations on them, retiring some styles and introducing others as time goes by. you can request them in most fabrics, and from time to time she also does other designs - slingbags, messengers, etc. they start at about US$18 for a wristlet and go up to about $42 for the largest totes. for the staples of the moment, the jan bag wristlets are very versatile and a good size, and are about $25, and i would get them if i didn't always carry books about with me.

another staple is the granny bag, which has ribbon edges and a rounded bottom. these are large and are about 42cmx28cm.

the jenny bags, smaller affairs, which look like this. they have a very cunningly sewn-on clasp too:

then there are the jan bags, which look like this. these are quite roomy and can hold a file folder
