I am using the tikzlibrary decorations.markings to put arrowhead on arbitrary places on some lines. My code is the following:
\begin{tikzpicture}[arrowmark/.style 2 args={decoration={markings,mark=at position #1 with \arrow{#2}}}]
\draw[
postaction={decorate},
arrowmark={.15}{ >},
] (0,1) to (3,1);
\end{tikzpicture}
Now I want to make the arrowhead a bit bigger and a bit thicker. I read some hints in the manual and several questions here but I can't figure out how to implement this in my code.
