what do I do? I have the S U G A R C R A F T gun.. and had the makins gun... but neither of these make big ropes... what is the secret.. cause when I go rolling them with my hands they don't stay even...

Find two dowel the size you want your rope and roll your rope between the dowels. wa la

And then I have a mold that's not silicone but you just lay the smooth rope into it to make the ropey design marks on it. But this one is pretty cool too.

And here's Earlene's classic method, using those (handbusting) guns.

Ah, I never thought about dowels! Awesome! Voila, indeed!
