"Would it make sense to place a pillow to the side of the hip for support when doing 90 and 45 degree leg stretches? "  -  Sure, you can put a pillow under the leg when doing a 90 degree stretch if the client is really stiff so that the stretch cannot go so far.

"When stretching the calf muscles, would you change to foot position when giving more attention to the calves? By changing meaning twisting the foot inward or outward? "  -  No, the best foot position is without any twist for the ankle stretch (the last stretch in this module). Twisting the foot can feel bad for the ankle.

"I notice there is a bodyweight pull of the leg when you transition during foot massage. Is there a particular reason for doing this?"  -  There is a bodyweight pull when you lift both legs together because in this way you can use your body weight to lift instead of your arm muscles. This can be used when lifting both legs or only one.

"How long would you suggest a session last for?"  -  Thai Massage sessions are ideally longer than typical table massage sessions. Personally, I never did shorter sessions than 2 hours. This might not be possible or practical for you, but whenever possible, try to do longer sessions. It is difficult to squeeze the Thai Massage work into one hour. It can be done, but you will have to skip some techniques.

"However when it comes to compression with forearm on the thigh I have to work on pressure as there is inconsistency. "Sometimes it is painful sometimes it feels great".  -  Try to not focus on 'pressure', but on feeling. Try to feel what is the right position of your forearm, where it feels just right to you (and subsequently to your client). Try to use less pressure and more feeling. Once you got the feeling, you can always add more pressure.
