We recommend using one fastener sticker in each of the four corners of the window frame, with additional strips as needed along the top and sides, depending on the size of the window.
Along the top, we suggest placing fastener stickers at approximately 40cm intervals. Down the sides, use as required to hold the fabric close to the window frame.
It is important to stick these to your window frame correctly first time as removing and replacing them will weaken the adhesive.
Once in place, press firmly and leave for 24 hours before use to allow the adhesive to bond fully.
