I’ve been gradually updating my son’s bedroom with several DIY’s and the last job on the list was to sort out his sash windows. Yellowed and peeling, the tired timber sashes were also dressed in curtains aged over ten years and were therefore faded, ripped and stained. Along one window, a plank of wood containing a single strip of velcro ran along the top (which I assume was left over from an old window dressing installed by the previous owners). 

After upcycling a pine wardrobe with bobbin detailing, creating a fun window seat and installing a mural along one wall, I wanted to continue being creative in my kids’ bedroom. After stripping and painting the sash frames blue and installing new ticking stripe curtains, I decided to create a low-cost, wavy-edged pelmet on the main window using plywood.

Wavy interiors continue to be a huge trend within interior design and after purchasing a colourful wavy-edged rug for his room, I decided to continue with the wavy theme over onto the pelmet. I’d remove the velcro from the existing wood plank and I’d use this as a base upon which to attach the DIY wood design.

All I needed to do was buy an inexpensive sheet of plywood from the DIY store and cut it into the required length and shape. As I am not a carpenter and as storage space in my house is tight, I wanted to invest in a small, budget-friendly, hand-held tool that not only cut perfectly straight lines, it also allowed me to create the wavy shape in the wood that I was after.

After reading some reviews online, I decided to invest in the HYCHIKA Electric Mini Circular Saw, a compact tool that was suitable for cutting softwood (amongst other materials like plastic and metal). Light and easy to hold with one hand, its petite size made it portable, easy to store when not in use and the perfect tool for those small DIY jobs around the house. As it is so bijou, as a power tool this mini-saw didn’t feel overwhelming to use and I felt confident cutting with it as an occasional DIYer.

To start making the pelmet, I used an aluminium ruler and measured out the length that it needed to be, before using a semi-circle protractor to draw an even wave along the plywood piece. 

Once my wavy pelmet was outlined onto the plywood, I used the scale ruler that comes with the HYCHIKA Electric Mini Circular Saw to cut the plywood to size via a perfectly straight line, as this parallel guide attachment guided my cuts with ease. 

I then used the Electric Mini Circular Saw to carefully create the wave. I reduced the cutting depth to ‘5’ which allowed me to cut the wavy pattern easily as opposed to a deeper cut setting (which I used for the straight lines) and gave the edge a light sand with a sanding block.

After removing any sawdust particles, I primed and then painted the pelmet face with this gorgeous reddish brown called ‘Loving Orange’ by Yes Colours. I’ve used this shade elsewhere in my son’s room and it’s such a lovely paint colour that changes in depth throughout the day. 

Since I already had a wood plank installed, I simply removed the velcro and attached the light plywood pelmet with some double-sided strong tape adhesive. However, to install your own base, simply purchase a slim pine plank from the DIY store, cut it down in length using the HYCHIKA Electric Mini Circular Saw and attach it to the wall using floating or discreet shelf brackets. Apply the double-sided tape on the edge of the plank facing the room and apply your plywood pelmet. 

This is how the window looks now! I’m so happy with this cute, trend-led look and the design and colour really ties in with the wavy rug and the rest of the room for a cohesive space.
