Decoration Colours
Lesson 4 of 5
20 min
At a wedding, a graduation or a school prize-giving, almost every photo is taken in front of the same spot: the decorated wall or stage behind the main table. That backdrop appears in hundreds of pictures that families keep for years. At home the walls, floor and ceiling are the background to everything else in the room.
A good background makes the people and objects in front of it look their best. A poor one fights with them or hides them. In this lesson you will learn the principles for designing a decorative background, the common types, and how to work out the fabric for an event backdrop.
The background is the surface or area behind the main objects. The foreground is what stands in front of it and should catch the eye: the couple's seats, a speaker, a display of cakes, the words on a notice.
| Type | Examples | Good points | Weak points |
|---|---|---|---|
| Painted wall | one colour, two colours with a border, a mural | lasts for years, easy to clean | takes time; not for a one-day event |
| Fabric drapes | gathered voile or satin in the theme colours | quick to put up, soft, can be reused | creases, catches fire easily, needs a frame |
| Woven panels and mats | papyrus or sisal mats, baskets, woven plates | local, natural texture, Rwandan character | can look busy if there are too many |
| Leaf and flower walls | real or artificial leaves, flower panels | fresh and lively, good for photos | fresh plants wilt; artificial ones cost more |
| Printed banners | a school name, a couple's names, a logo pattern | carries a message | printing cost; words must be large and clear |

Look at the wedding stage in the photo.
Ishimwe's class is making a drape backdrop for a graduation stage 4 m wide and 2.5 m high. The fabric is sold 1.5 m wide at 2,500 Frw per metre. To look full, gathered drapes need twice the width they cover. Each drop needs an extra 20 cm for the top casing and the bottom hem.
Step 1: flat width needed. 4 m × 2 = 8 m.
Step 2: number of widths of fabric. 8 ÷ 1.5 = 5.3, so round up to 6 widths. Five would be too few.
Step 3: length of each width. 2.5 m + 0.2 m = 2.7 m.
Step 4: total fabric. 6 × 2.7 = 16.2 m.
Step 5: cost. 16.2 × 2,500 = 40,500 Frw.
Tip
Memory hook: the background is the stage, not the star. Quiet behind loud, light behind dark (or dark behind light), plain behind pattern. In fabric questions, always round the number of widths UP, and add the hem allowance to every drop.
Explain the difference between the background and the foreground of a display.
Solution. The background is the surface behind the display, such as the notice-board paper. The foreground is what is shown in front of it and should catch the eye, such as the pictures and headings.
Which background colour would make black writing on a class notice board easiest to read: dark blue, pale yellow or red? Why?
Solution. Pale yellow. Black and pale yellow are far apart in value, so the letters stand out clearly. On dark blue or red the dark letters would be hard to see.
A couple will wear bright, busy kitenge. The decorator plans a backdrop of the same busy kitenge. Evaluate the plan.
Solution. It breaks the rule of pattern against plain: the couple would blend into the background and the photos would look confusing. A plain drape in one colour taken from the kitenge would make the couple stand out while keeping the colours in harmony.
A drape must cover a wall 3 m wide and 2.2 m high, gathered to twice the width, using fabric 1.5 m wide at 3,000 Frw per metre, with 20 cm extra per drop. Find the fabric needed and its cost.
Solution. Flat width = 3 × 2 = 6 m. Widths = 6 ÷ 1.5 = 4. Each drop = 2.2 + 0.2 = 2.4 m. Fabric = 4 × 2.4 = 9.6 m. Cost = 9.6 × 3,000 = 28,800 Frw.
