working/sewing with felted items.

I know HOW to felt but am looking for helpful suggestions---any kind---for sewing/cutting/designing with the item once it is felted.

I have just started doing this with wool sweaters from thrift shops.

Have done some reading on-line about it and see designs made......do you have a favorite website for this?

Have one purse made........and not sure I am happy with it.

Thought I would ask for suggestions from anyone experienced in this...............

Any help greatly appreciated!!! TIA!!!
