Would you use a funnel to pour the mix into the mold?
A funnel's not necessary! Just SLOWLY pour directly from the mixing container from about 10-12" above the top of the mold walls. The stream will be thin and easy to direct.
For a more detailed explanation, read the mold making steps in Lesson 3.

You can use a funnel or something similar and hold it in place with clay around. But you need to make vents to allow the air be able to get out otherwise it would be fighting with the silicone you ere pouring. If you make holes as air vent, have clay ready to pliUg those holes once the rubber start to show.
If you feel that you need a funnel to fill your mold how about making the funnel part of your mold? Make the sprue (inlet) with a pouring cup / funnel included!
