Hi, Our puppet ministry uses styrofoam pieces, about 6" tall by 2 to 4 feet wrapped in duct tape, to stand on for height adjustment for performances.  Being a youth ministry we have a lot of different heights involved and it seems to work fairly well.  Because each song/scene uses a different puppeteer, the stage has to be quickly adjustable.  My question is...is there an even better way?  I need to make some more and have the styrofoam (good duct tape is expensive) but willing to go there if that is best???

We have used several things including hand made wooden stools, purchased fold up stools from creativemin and stacked foam puzzle toys like this hot glued together.  But our favorite is a black plastic step stool purchased from Dollar General.  They have a slot in the middle for carrying and they stack! But for kneeling we like the foam puzzle pieces stacked and glued.  You can make them any height you want.  I watch for them at yard sales and such.
HTH!

The last height adjustors we used were the pink insulation foam rectangles foot by 3 foot and put them together with really large rubber bands that we got at office supply store.  But you needed to use 3 or 4 and make sure they are tight so they don't slip.  that way you could quickly slip another rectangle in or take one out as they grow.  My last team was all adults and we did not have to adjust height, it was so nice.

Thanks for more ideas!

Just a pic of some big ones I made.  Our pulpit area is 9 inches tall and not very wide.  These will sit next to that on each side to widen our stage area.
