I decided to finish the library vignette this afternoon. I slipped a piece of paper on the floor and taped it in place so I would be able to mark the curve of the plexiglass and use the paper as a pattern to cut out the carpet.
Then I put the plexiglass in place....and the minute it slipped in place....I thought "how the heck am I going to get it out?"
Good question - and I have no idea yet what the answer is!
Hope I can figure it out soon and complete this.
