Choosing flowers and a fabric when setting a table is fun but not always easy.
Two ways to go could be bold and dramatic or soft and pretty.
Dark red tulips in a clear glass vase combined with a graphically bold fabric can be fun and interesting for a spring lunch.
You probably need to use some plain china and glasses not to make it look too busy.
A row of small vases with early iris in the middle of a long runner. The pretty purple of the iris is picked up in the ikat fabric. The fabric is really a long narrow scarf but it works just as well on a table.
