Clara´s homework the other day was for her to bring in some vowel flashcards. No problem.
I cut the cardboard, wrote the vowels, and after a grand total of 5 minutes, we were set!
Then, I noticed the box that I cut the cardboard from. I don´t know that I´d be able to send those letters with her to school if we lived in the US!
However, as we don´t, I didn´t think twice about it.
