Transfer border tiles are rare. Monochrome tiles are less expensive than multicolour. They can still be spectacular tiles, one of my top ten favourites is a green glazed Art Nouveau tile. You can always buy a multicolour tile as a special treat. Or you can even collect a particular colour, for example green and brown majolica tiles are common but pink tiles less so.
Quartered tiles are consistently the lowest cost colourful majolica tiles.
Mostly Art Nouveau but many Victorian floral designs too. The full range of majolica colours come up from time to time and also some more unusual techniques like barbotine. Look very good when displayed together as for example in a table top or splashback. Avoid leading manufacturers names whose tiles demand a premium price. Pick a subject Floral and geometric floral patterns are found most often but the range of subjects is vast.
