Theater/Musicals papers or embellishments

This is the closest I can find

Reminisce also has another collection Live in Concert that might work for you jediannie

Brutus Monroe: Marquee stamp (image of sign; there is also a matching die) and Marquee Sentiments stamp set (blocked out letters for custom titles as well as “…THE MUSICAL”, “CONGRATS”, “BREAK A LEG”, and “NOW SHOWING”. I think he may have some other stage stamps/dies, too. I recently got these on sale at Simon Says Stamp, and I’m not sure if it is still current or being discontinued, so there may be a risk of it disappearing soon.

Ralph Tyndall with Hero Arts has a stamp set called “Center Stage” that features stage lights that can hang from a light bar above, actor silhouettes, dancer silhouettes, musician silhouettes, comedy/drama masks, & stage/theater-related sentiments. He also has a die called Center Stage Crowd that makes it look like an audience (facing toward the stage, away from the person looking at the card or layout) and a Color Layering Stage Curtain Stencils set that makes a layered theatre curtain and stage floor for background use. You can get a coordinating die for the stencil set called Stage Curtain Fancy Die.

Kindred Stamps also has a die (Stage Curtain Craft Die), but I’m not sure how long it will remain available or if it will be restocked if it sells out. It is currently available.

jediannie I fell in love with the Kaisercraft "On Stage" line-it's hard to find but there is a pad of it here www.cranberrycat.com/KaiserCraftOnStage.htm and I highly recommend this pad as it has lots of cut aparts, etc. This line is also great for concerts. I also bought the stamp set, so I wanted to let you know if you'd like me to stamp some sentiments out I am more than happy to do that and pop them in the mail. Just pm me.  

DS was in many musicals, so needed options!  

I look for theater supplies a lot, mostly have digital kits:

For Seussical - maybe pick up a Dr. Seuss book from a thrift shop? Red & white striped paper?
