🌸 How to Plan a Crochet Flower Curtain

Measure, calculate and choose your yarn before you start — with free curtain patterns

A crochet flower curtain is one of the most impressive pieces you can make for your home. Hanging strands of flowers soften a doorway, frame a window or turn a plain wall into a feature. But it is also a big project, and most of the frustration comes before the first stitch: How many flowers do I need? How long should each strand be? How much yarn should I buy? How do I hang it so it doesn’t tangle?

This guide answers all of those questions with simple calculations you can adapt to any window or door, and links to the free curtain patterns on this blog.

Step 1: Choose the Style

Style	Look	Best for
Hanging strands	Separate vertical strings of flowers that move freely	Doorways, room dividers, wall décor
Joined mesh	Flowers joined to each other into one panel	Windows where you want more privacy
Valance	A short band of flowers across the top	Kitchen and small windows
Tie-back accent	A few strands at the sides of a fabric curtain	Adding colour without a big project

The strand style is the easiest to plan and to make in stages — you can finish one strand at a time and hang it immediately.

Step 2: Measure Your Space

1. Measure the width of the rod or the area you want to cover.
2. Measure the drop: from the rod to where you want the curtain to end (for a doorway, usually 3–5 cm above the floor so it doesn’t drag).
3. Decide the spacing between strands. About 5–8 cm gives a full look; 10–15 cm gives a light, airy look.

Step 3: Calculate the Number of Strands and Flowers

Use these two formulas:

Strands = width ÷ spacing between strands
Flowers per strand = drop ÷ (flower diameter + gap between flowers)

Example for a doorway 90 cm wide and 200 cm high, with 7 cm flowers:

Choice	Calculation	Result
Strands every 7.5 cm	90 ÷ 7.5	12 strands
Flower 7 cm + gap 5 cm	200 ÷ 12	about 16 flowers per strand
Total flowers	12 × 16	about 192 flowers

That number can sound scary — but most flowers take only 10–20 minutes, and many people love making them while watching a series. Making flowers in batches of one colour at a time is much faster than switching colours constantly.

💡 Tip: try a half curtain first

Make every second strand first and hang them. You may love the lighter look and decide you don’t need the full number — or you’ll see exactly where more colour is needed.

Step 4: Estimate How Much Yarn You Need

The most reliable method is to measure your own flower:

1. Make one complete flower with your chosen yarn and hook.
2. Weigh it on a kitchen scale (or unravel it and measure the length).
3. Multiply by the total number of flowers.
4. Add the yarn for the chains between flowers: drop length × number of strands × about 1.5 (chains use more yarn than their length).
5. Add 15–20 % extra for tails, mistakes and a few spare flowers.

For example, if one flower weighs 3 g and you need 192 flowers, that is about 576 g of yarn for the flowers alone — plus the connecting chains and the safety margin. Buy all the yarn for each colour from the same dye lot.

Step 5: Choose Yarn and Hook

For curtains I recommend cotton or a cotton blend in light to medium weight. Cotton hangs straight, holds the flower shape, and keeps its colour in sunlight better than many acrylics. A slightly smaller hook than usual makes firmer petals that don’t droop. See my yarn weights guide and hook sizes chart for details.

Step 6: Plan the Colours

• Gradient: light colours at the top fading to dark at the bottom — or the reverse.
• Two-tone: alternating colours, like the royal blue and gold curtain.
• Seasonal: red, green and gold for the Christmas flower curtain.
• Elegant: deep jewel tones with a metallic accent, like the emerald and champagne gold version.

Sketch the curtain on paper with coloured pencils before you buy yarn. It takes ten minutes and prevents expensive surprises.

Step 7: Assemble and Hang

1. Crochet a chain at the top of each strand long enough to wrap around the rod, plus a little extra.
2. Join flowers along each strand with the same number of chains between them, so all strands line up.
3. Weave in all ends securely — curtains move constantly (see my finishing guide).
4. Block or lightly steam the flowers so they lie flat.
5. Hang strands by tying them around the rod, or attach them to curtain rings or a wooden dowel.
6. Optionally, add a small bead or a heavier flower at the bottom of each strand to keep it straight.

Care and Maintenance

• Dust regularly with a soft brush or a hairdryer on cool.
• Hand wash strands individually in cool water if needed and dry them flat.
• Avoid long, direct afternoon sun on bright colours, which can fade over time.

Frequently Asked Questions

How long does a crochet flower curtain take?

It depends entirely on size. A small window valance can be finished in a weekend; a full doorway curtain with nearly 200 flowers is usually a project of several weeks of relaxed evening crochet.

Will the strands tangle?

Strands with a little weight at the bottom and firm, flat flowers tangle much less. Space them at least 5 cm apart.
