doing acrylic nails yourself is generally not recommended, unless you are a nail tech and you know what you are doing. It's a very particular and finicky process, and it's very easy to get wrong - and getting it wrong could mean damage to your nails which is permanent or takes a long time to heal.
if you want to look into what's required to do them yourself a google search should bring up tutorials.
i advise you to proceed with caution... i've had my nails damaged by getting acrylics done professionally and it was many months until they were better.
