You might also find some items available through eBay, but make sure that the feedback on the seller is good before you purchase anything. I am considering stitching some of the items I need, so that I put creative energy into the item, making it more personal to me. Right now I am stitching a green double happiness symbol ready for activation tomorrow. If you have a scanner, you can scan the symbol into your computer, enlarge it to the size you need, then print it out, square it off and start stitching (of course, if you know how to embroider freestyle, you don't have to square the design off but for those of us who use counted methods, squaring off is essential!). I have found some useful charts on a UK craft site, and the US is usually better than the UK in this area, so if you can do cross stitch or other forms of embroidery, you can make your own items. My next projects are the Diamond Feng Shui Diamond, the Illness Star Hexagram and the Conflict Star Hexagram. Then on to the larger items!!!
Hope this helps and the very best of luck in your search for the things you need.
