If a girl seems comfortable with you touching her it is a good sign?

We been friends for 7 months and I like her, Im starting to put my arm around her while walking like for long distances, putting my hand in her leg and tight for minutes while talking, recently putting my hand in her waist, and she seems to not care, and also at the end of the day she texted me she enjoy spending time with me so im sure she didn’t feel uncomfortable.
