@EmbQuilt,
Thank you so much for responding to me

Your help would be much appreciated! Please stay in touch with me as I progress in making this quilt. Your advice was very helpful. I don't think I know anyone who is savvy with an EQ program... isn't that an audio equalizer, if I'm not mistaken? Do you know of any other computer programs I could use to achieve these results?
Also, sorry, but what do you mean by the "dimensions"?
Thank you
