cushions are easy to sew right?

[RuByMaMa]

Just that really. Total sewing novice here who would like to update her living room (cheaply) by sewing some nice new cushion covers. I haven't got the actual cushions themselves yet but just wondered if there's any tips or basic principles to follow when doing them? I do have access to a sewing machine so won't be labouring over them by hand thankfully! TIA

Cushions are really easy, true. However, there are a couple of things to keep in mind: you will need a cushion 'filler' larger than the cushion cover (this is rather illogical, but if you match them perfectly the cushion cover will be rather loose). Also (esp. if you're new to sewing), make sure you use a cord or some other trim on the edges - that way, any 'wiggly' seams won't be as noticeable and you'll get much neater professional looking cushions.
Cost wise - I'd say you may not actually win anything by making them yourself. That's because the main cost drain is the fabric. For a manufacturer with an established production line, the cost of labour for each cushion cover is near zero, and they buy the fabric in bulk with savings you won't get buying retail.

The only tricky bit for a novice is zip insertion, but you can get round this by making an envelope construction

And I agree with elk on the cost

Envelope construction for the win - super SUPER easy (hem the short ends, sew up the sides and done...), but I agree with Elk - fabric is surprisingly expensive if you're even slightly choosy about things.

Envelope cushions are easy, you just need to make them an inch or half and inch smaller than the insert (depending how full the cushion is that you buy) and make sure that you have a big enough overlap.

I prefer my own cushions as I only buy feather innards and really nice fabrics, I usually have a stash of fabric so I can mix and match and get a nice look. Most fabric shops have an off cut table and you can get ends for half the normal price or less.

Once I have a piece of fabric I work out what sizes of cushion I can get from it rather then the other way around, that way I can always buy off cuts. If you get into patch-working bits you can save even more money.

I have a meter rule and that dressmaker chalk (or even a felt tip pen if it comes to it and won't show through), once you have drawn straight lines and pinned your fabric you can't go to far wrong.

Thanks for all your responses! Have taken on board what is being said about cost and work out how much i would need to spend on this compared to the cost of just buying new. Thanks again!
