I HIGHLY recommend Stitch-n-Frame.net They have Thursday
specials and frequently have batiks on sale.
I noticed in an e-mail from Webfabrics.net that they are having a sale of the great 1895 line of Hoffman batiks. However, a sale
on Hoffmans which are often $10 or even $10.50/yd is $7 which
still adds up rapidly. The sale is only until 2/12/11.
There are other web sites, like Batiks Plus, and you can look at
their sale/clearance sections but if you want to get started and not wait for sales, I'd take a look at the first two.
