Roman blind kits, small and large, white (Knebworth SG3)

This is two Roman blind kits from Dunelm. One small, one large (width 90cm, length up to 110cm) / (width 122cm, length up to 183cm).
Original packing, unused. Says it has easy to follow instructions (I've not tried). I think it includes fabric although that might just be a liner and you provide your own outer layer to match your decor. What I can see is white.
