I am going to give out a holiday spice bundle to my family and friends
to which I plan to attach instructions.  Do I use quotation marks for
this?  Ex.  "Place the muslin bag into a kettle or pan. Add a quart of
water and bring to a boil. Turn down the heat to low and simmer for a
while.  Your house will smell wonderful!"  Is it correct to put
quotations around the directions or is it unnecessary?

Hi sheesh,

Quotation marks would be unnecessary in this case, since the writing
is from you directly to the recipient and you are not quoting someone
else's instructions.

The Purdue University Online Writing Lab has a page on uses of quotation marks.

Wikipedia's article probably has much more than you want to know.
