I have posted a new tutorial on how to design a horseshoe, along with the cutting file for it, as well as the cutting file for the Shamrock Popup Card. The technique used for creating the Shamrock card is the same as that used for creating the Heart Popup Card demonstrated during the February 14 Q&A Webinar, except for the original shape used.
You will find the tutorial called II.19_Make a Horseshoe posted at the bottom of the Basic Lessons folder in the Files section at the MTC_Tuts Yahoo group http://groups.yahoo.com/group/MTC_Tuts/files/02_Basic Lessons/
The Horseshoe_JF.mtc and ShamrockPopupCard_JF.mtc cutting files are in the Shared MTC Files folder of the Files sectionhttp://groups.yahoo.com/group/MTC_Tuts/files/Shared MTC Files/
