I'm a new-ish sewer. I only recently started getting serious about it (dreaming about patterns, hoarding fabric, the works!) now that I have a toddler daughter who I can make the cutest little clothes for!
Oh, listen to this sad little tale....
We went to a wedding! My brother-in-law got married, and I decided, how cute would it be to sew matching flower-girl dresses for my one-and-a-half year old, and my 5 year-old niece... Well, word to the wise, don't start fancy sewing projects when you are working full-time, have an active toddler, and are in your ninth month of pregnancy :-)
Anyways, I worked at it, slowly but surely. I made up my own pattern, and hopped right in... Each step was a learning experience - how to add the lining, how to sew an invisible zipper - exciting and exhilarating! (and as I explained to eyebrow-raising family member, very therapeutic activity for forgetting the aches of a big belly).
The dresses have a beautiful fabric for the bodice, lined. The bottoms are full circle skirts of satin and organza - super-flowy and twirly. Here's a picture of my niece in hers - quite the model!

Ah, now here is the sad part of the story. A month before the wedding, the dresses were just about complete, sans the hems, and I had my second baby. Wow, life was a bit hectic, and definitely no time for sewing! But I found a bit of time, and set to work on the hem on the smaller dress... Yikes! Too much fabric to fold over and sew down, not to mention it being a
circle skirt. I bought a rolled hem foot, and tried that. It made a nasty mess of the organza. But I managed a pathetic looking hem on the satin. I ended up doing a very tight zigzag on the organza, which ate up and stretched the material, and it was, well, awful.
see for yourself, my sad sad seams...

oh how i wished i had a serger! and just serge the edge away in a beautiful crisp satin rolled edge!
Well, there was no way I was attempting the larger dress and the zillion yards of material in that hem. I took to a tailor, and she charged me $25.
Ouch.
It hurt. I had to pay a hefty sum to finish off my own creation, and the shame! Oh, I can see them clearly at the tailor's, wrinkling their noses, "what amateurish sewing! look at these terrible edges!"
And so, there it is. I will not be attempting fancy sewing in the near future, not without a serger (ahem hem). We'll stick to unfinished knits and their rolled-up edges.
Oh please, won't you encourage a novice sewer and send a serger my way??
