The first thing is where to find them. Most are under the Extra's menu located along the Top menu bar:
There are a few collars that get added to drop down menu's when you buy Style sets, like the Shawl and Tailored collar from the Style set 2 get added to the Neck Group.
Second to bring up a collar from the Extra's menu you must click on either Joined at Front or Joined at Back. Note that the word "Collars:" will always be ghosted it has a colon behind it to denote a Title. There are other Title menu's like this in Garment Designer, it means the functions are beneath the Title.
Third the Collars are separated into Stand, Full Roll, Partial Roll, Flat and Hood. You will need to know the construction of the collar pattern pieces to find the correct collar you are looking for. Susan has done a great job in the manual of explaining the terminology of the collar. Chapter 8 page 25. If you need additional help you can also purchase our Fun Fashion collars PDF booklet. It has more detailed and in-depth information regarding collar construction.
With those key points you are well on your way to be able to add a collar to any design. Please feel free to call or email if you have any questions.
