Got mine almost done tonight. Put on a coat of Seal Krete last night. I was really surprised at how heavy and sturdy its become. I did use 64 cut outs on mine; one each at 90 degrees and then filled in by splitting the halves until I had fifteen in between each original 4. Lowes had the Seal Krete on sale, a 5 gallon bucket for $23 marked down from $56.
Working at a grocery store, I just score 3 banana boxes FULL of rolls of register tape. The coupons are all expired so they were tossing them out. With hopes this will work for paper mache for this project.
