To make this envelope cushion cover to fit a 45cm square cushion you'll need:
A piece of yellow material for the Lego man and a Lego man template. You can make this any size you like.
A piece of fusible interfacing so you can iron your Lego man onto your cushion fabric.
Cushion fabric - three pieces measuring 18"x18" (the front of the cushion), 18"x14, and 18"x12" (the two back pieces which will overlap creating an envelope opening. No zips!!!)
Print out and trace your Lego man onto your fusible interfacing then iron that onto your yellow fabric. The interfacing I use is double sided so I ironed it onto the yellow fabric then cut out the yellow Lego man, peel off the backing and...
These pieces will still measure 18". You are folding, ironing and sewing the 14" side and 12" side.
I like to use my 14" back piece first, then the 12" inch piece. This gives the rear of the cushion a nice long covering on its envelope back.
I say this with my tongue firmly in my cheek! I am very much in the camp of 'close enough, good enough' with my sewing, cutting and measuring!
I've made two of those now for boy's birthday presents this weekend. I may add a mini figure with them for good measure in case the birthday boy's are not huge fans of soft furnishings!
Told you it was easy!
