i am making up some gift batches and i am wondering do your customers, friends, testers or other input givers prefer solid bars, swirls, vibrant colors, sedate or pale colors, no colors? colors that "match" the fragrance like strawberry soap is "supposed" to be red. i have a few batches i want to make but i am torn mostly between solids and swirls so i need opinions. what is your "crowd pleasers" look wise...?
