hi. have been following links and the info has been helpful - here comes the but - i am having a problem with pattern making from the maquette. have been testing out the large patterns (understand how to enlarge) in cardboard and they seem fine, until i make them up in foam (am using pe30). any suggestions?
oh and has anybody used suede lycra as a covering?
thanks
The problems you are encountering may have to to with the thickness and the "squish-ability" of the foam versus your cardboard pattern.
Remember: you're cutting the pattern out of foam that is probably 1/2 inch thick. That means your pieces will be squished smaller towards the inside of the shape you're building and stretched larger towards the outside of the shape you're building.
Imagine a ball shape made of 1/2 inch thick foam. If you measure the exterior of the ball and it's 6 inches in diameter, the INTERIOR diameter of the ball (the hollow space inside) will be somewhere near 5 inches in diameter. Because there's a 1/2 inch wall thickness all the way around.
Patterning to exact dimensions is VERY hard to do. Making a pattern for the foam part and the covering at the same time requires a lot of mathematical skill (that myself and many other puppeteers don't posess).
So let me offer this idea:
Start by making your foam "skull". Make sure it works properly. In fact. if you have enough material, make two... just in case.
1) Create a custom pattern over the top of it by taking regular duct tape and de-tacking it. That means stick it to your pants first before you apply it to the foam piece.
2) Lay the tape on the surface in two to three layers... criss-crossing the pieces so you bridge any seams between the pieces.
Once you've covered the foam, geta sharpie marker and figure out where the seam lines should go. Draw them onto the tape. Make special thought about how you will make this shape LAY FLAT once the pattern is away.
3) Take a nice, sharp pair of trimming scissors (the little ones with the nice sharp blades) and carefully cut the TAPE along the lines. If you've de-tacked the tape well enough, the pattern should lift off the foam head.
But this is also why you should make a spare... sometimes the tape just sticks. And you tear the foam or have to cut it to get the pattern away.
4) Once you have the tape pattern, lay it out on large craft paper and trace it flat.
After you use the pattern once, you'll get a feel for where it'll need better fitting to look good on the foam shape.
Maybe this wasn't the info you needed.. but there it is...
