You’re welcome believe me lol. Yes as far as tutorials go serpa design is great. My only criticism is his use of bituminous clay as a filler since it doesn’t last to long and deteriorates when dry. Also I apologize, I should have clarified that a small practice build shouldn’t house any animals as it would definitely be too small. It’s really just a way to practice some of the techniques. Think of it as a sketch on scrap paper before committing paint to a canvas. The pur foam takes a few tries to get it right so I always recommend a trial first. It’s not cheap either if you use several cans. You could even practice on cardboard first and toss it out if it doesn’t look right. Also if you want your foam to dry spray it with a spray bottle filled with water. It will cure faster.
