The work shown in this book is lovely and quite sophisticated, particularly in terms of color combinations used. However, especially as compared side-by-side with "Quilling" by Jane Jenkins, it seems that Ms. Choi is more interested in showcasing her work than really teaching others to quill as the instructions given are terse and skimpy. It also seems more suited to people who want a specific project to copy rather than those of us who'd like generalized instruction and inspiration in order to create our own designs.
Also -- and again in comparison with the Jenkins book -- the actual techniques shown and used in the projects are quite limited in scope, i.e. mostly closed loose and tight coils. A mere two pages are devoted to other styles such as loop husking and fringing, and no-where near the variety of examples are shown. Ms. Jenkins devotes 10 pages to alternate side looping alone, with two of those being lovely clear photos of technique.
There are also quite a few typographical errors within which doesn't really matter in a book like this, and yet ... (mind you, I sort-of liked "nameless wildflowers" in the introduction. Presumably she meant "countless"!)
Worth owning, mind you, as long as it's only one of a group of quilling books. If I could only have one, however, it wouldn't be this one.
