So I got all ready to address my invitations but I noticed that I only have a Bic black pen. I got paranoid that it will take away from how nice and formal the invitations look. I don't know if I'm over thinking it though.
Have you used a regular pen if you addressed evelopes yourself?
If not, what did you use?
Has anyone bought a calligraphy pen and used it just to write in normal handwriting, not knowing calligraphy?
Any help is greatly appreciated!

235 invited so far!

144 are ready to party!

91 will be missing out!

0 are MIA!
Re: Using a calligraphy pen when I don't know calligraphy?
If you can print, you can do calligraphy if you have the pen
If you don't want to use a calligraphy pen, you could at least consider one of those gel pens for a sleeker, more consistent line - I'm a fan of the Pilot G2 series.
The gold paint type pen looked way better, partly because the end was a little softer, but sometimes it did make blobs of gold ink, especially towards the end when the pen was getting old.
