While browsing, I chanced upon to read about paper mache. Read through what it can be used for and found it interesting to give it a try.
DD1 was interested as well and she did the pasting of papers on the balloon. Couldn't click photos while we were at it since my hands too were filled with the flour mix, all the while, taking care of DD2 that she would not spill all the flour mix. ☺☺☺
