Hello. I have been struggling with fondant rope boarders. I searched through the forum about techniques. Everyone talks about how great the extruder guns are. Clay extruder and "cake decorating" extruders all seem to hold small amounts of fondant. How do you keep from breaking your rope while unscrewing and adding more fondant to make one rope without seams. Rolling by hand seems to never be right. It breaks. My goal is to go around an 8" cake. What have I missed? 

Thanks to anyone that can help.

That's  very interesting. Thank you. 

bu i just use a silicone mold -- i make the rope as long as i want it and just keep it moving through the mold -- but you can join them seamlessly too -- lay them on top of each other and cut diagonally through each, discard the cut off bits -- it will then join perfectly

this will save your hands big time

thanks for the ideas! i ended up buying the cookie press that earlenescakes recommended. short on time, I used it by hand, it did work well, but her system will be nice for future. I also searched everywhere for a plain rope mold. I ended up with seams only because I underestimated the amount of fondant. live and learn. always improving.  thank you for your help.
