Minimalist Window Ideas

If you take a minimalist approach to your Christmas decorations, indoor curtain lights are our go-to. Creating the illusion of falling snow, twinkling Christmas curtain lights capture the spirit of the season. If you want a homely feel, choose warm Christmas window lights, or go with cold white lights for an icy, glamorous look. 

Classic and Traditional Window Displays

Nothing beats the cosy appeal of a dimly lit Christmassy home. So, if you’re looking to create that oh-so-desirable classic Christmas look for your home, scatter a few battery-operated candles across your windowsill. You could even complete your window display with a festive garland for that added seasonal touch. Choose battery-flickering candles to add ambience and really make your window glow. 

Colourful and Fun Window Lights

Christmas is all about bright lights, jewel-toned colours, and vibrant personalities. So, take inspiration from the season’s bright lights and cheery characters when creating your window display. Find star-shaped hanging lights and line your windowsill with Christmas figures and light-up reindeer. The perfect approach for families; these decorations are certain to create special memories for the little ones. 

How to Choose the Best Christmas Lights for Your Windows

When creating your window display, it's worth thinking about both style and function. 

  • Battery Vs Plug-in: Consider factors like whether you have a nearby socket and how much of your cable will end up being on display.
  • Indoor vs Outdoor Rated: If you’re considering outdoor Christmas lights for your window, make sure they’re weatherproof and have at least an IP44 rating. 
  • Why LED?: LED lights are cool to the touch, making them safe near curtains. LED lights also use up to 90% less energy than traditional incandescent bulbs. 
  • White Vs Multi-coloured: What atmosphere are you looking to create? Choose warm white lights for a cosy ambience and multi-coloured lights to embrace Christmas’ nostalgic, playful style. 

What is the Best Way to Hang Christmas Lights on a Window?

Everyone has their own approach to decorating, but here’s how we recommend hanging your lights for the best results. 

  1. Choose your lights and style: Think about the look you’re trying to achieve, and let that inform your approach. Are you looking to transform your home into a winter wonderland or embrace a warmer, more homely feel?
  2. Measure and plan your layout: If using plug-in lights, locate your nearest socket and plan your cable route. Consider the length of your lights in comparison to the length of your window frame. 
  3. Choose your hanging method: Consider which method will best support your window lights and where to place your hooks, suction cups, etc. 
  4. Hang and secure your lights: Start at the corner nearest the plug and work in one direction, keeping your spacing even.

How to Hang Christmas Lights in Windows Without Nails?

Nails are completely unnecessary when hanging Christmas lights in your window. They can be tricky to install and leave permanent marks on your walls. Instead, consider using adhesive hooks, suction cups, or even a tension rod.

  • Clear Adhesive Hooks: Best for uPVC and wooden frames, clear adhesive hooks stick seamlessly to your window frames. Simply press firmly for around 30 seconds, and wait before hanging. To remove them, use the tab to release the hook from the window frame. 
  • Suction Cup Clips: Best applied to the glass itself, suction cups are a secure way to hang window lights without damaging your walls, window frames, or windows. 
  • Tension Rod: Best for recessed windows or sash windows, tension rods allow you to securely hang Christmas lights without drilling holes.
