Hi, I am not 100% sure what you mean, but i add shortening to the paste and use the same ratio as you.
I always start any shape for the figure by making a nice smooth ball in my hands first, then it is easy to shape or roll and i don't have problems with cracking or anything.
Hope this helps :)
The tutorial is for a daffodil, but my friend said the cutter is for another flower?
HI, I had the same problem and found out by experimenting that I was using to much glue and making it to wet.
You only need a tiny amount and wait approx 10 seconds for it to go tacky, works every time for me now.
Hope this helps
