1) The document discusses how the author created ancillary products including an advert, CD case, and album art to promote a music video they produced, and ensured these products were effectively cross-promotional. 2) Techniques used included maintaining a consistent color scheme, style, and fonts across products to reflect the folk genre of the music and strengthen connections. Imagery also suggested themes from the music video like travel. 3) While the products were largely successful in cross-promoting each other through shared visual elements, the author notes the advert could have more explicitly promoted the music video over the album. Overall consistency of style and genre cues helped tie the ancillary works back to the main music product.
