The position of the word "say" "Having a vision of how many dominoes are needed and how to arrange a single, say, flower design can take weeks of careful planning." →Can I move the word "say" to another position in this sentence? Like this: "Having a vision of how many dominoes are needed and how to arrange, say, a single flower design can take weeks of careful planning." Is it correct? And, is there still another position that the word "say" can be put in? Thanks!
