Now, this is very easy and obvious, so I know a lot of you out there will have already done this - but for those of you a little bit like me, plodding along with their new toy, then this is for you.
Envelopes. Ridiculously easy with the brother scan and cut. Simple take an existing envelope, place it on your mat and scan, using the save data option. Save to your brother or USB stick thing.
Now fully open out the envelope - making sure you don't leave torn strands of the envelope poking out, otherwise it will scan these as well. Scan and save:
That's it, you now have an envelope and an insert for really posh envelopes!!
All you need to do now is choose your paper, bring up your saved template, make sure it's only picked up the scan lines (delete any you don't need) and then cut. For the insert, simply reduce the size a little so it'll fit neatly into your envelope:
Because you are using your brother, if you have the pens, you would be able to write on the envelope! You would also be able to cut a fancy top flap using one of the borders already installed on your machine.
And, you could even scan a scrap of paper, the same size of your card, and see if the envelopes you have stored will fit your card, before you need to start cutting. This means you would be able to alter the envelopes size so it will fit the actual card you have made. As long as it fits on your cutting mat, then your envelopes should be nice and easy from now on :)
