I don’t see anything in the Illinois Cottage Food Law relating hand washing and packaging.
The hand washing is for food sampling which is a separate issue from packaging. The sampling rules mention
“pre-packaged” food items that will be used for sampling, but again, that is a separate issue from what I am asking about.

Thanks for letting me know about the new law!

Often you are exempt from having to charge state sales tax, but you may need to charge local sales tax. It also depends on where you are selling (may have to charge it at a fair, for instance). http://forrager.com/faq/#sales-tax

You need to contact your health or ag dept. The requirements are different in every area.

The requirements are listed on this page: http://forrager.com/law/florida/
Please let me know if you have more questions.

Selling icing sheets should be allowed in most states, but selling online is not. You probably need to produce these in a commercial kitchen and contact your health dept for the necessary licenses.
