I get a LOT of questions concerned with changing the size of my Vintage Caravan Sewing Machine Cover so I decided to make a post, here, to suggest ways of doing this.
The finished size of the cover is: 20″ X 13″ X 9″
1). If you want to make an adjustment of several inches, this is the easiest way. It does not involve changing the curve so the overall shape will change a little if you adjust the width or height.
I recommend you double check the pattern against your machine to make sure the cover is big enough. It will probably need to be a bit bigger than your machine because of the way the cover curves in at the top corners. If you choose this option you may need to adjust the sizes of your door and windows. I suggest you complete Stage Two before cutting your door and windows fabric because then you will be able to see how much bigger/smaller you want to make the door and windows. Don’t forget to allow for the 1/4″ seam allowance around the edges of your main cover pieces.
2). If you want to make a dramatic change in size, you can rescale the pattern pieces using your printer – for example scale to 50% to make a half size version. Warning: If you choose this option, you will have to redraw all the seam allowances at 1/4″ and you will also have work out the sizes of the pieces that are given as measurements and do not have templates.
I hope this info is helpful :)
