hi ladies, i am not a newbie to quilting but I am to row, robins, so is it too late to jump in, can someone pm me with a bit of info, please, are all the blocks the same size, and if we are picking out a theme, well i have one, and if i read correctly , we also need a bit of fabric to make others in the swap , of their theme, and do them a row , am i right on this, of so, my theme being whimsical animals, and flowers,, with as much purple and red, and black, as possible, as the corresponding fabric, does that make any sense,
