I voted other because I could have voted for a couple of them.
I love it and think it is worth the effort.
I also think you should have some back-up professional choice if you are a new sewer.
I learned to sew last January and dipes were about the only things I made. I even drew my own patterns from dipes I already had. I made about 20 pocket dipes, some hemp flat dipes, and some extra covers in about 2 months. They worked really well.
I did spend some good money on them though buying hemp for inserts and MM fleece. I almost invested in a snap press but settled for aplix which worked fine.
I don't have time to sew dipes now and have only made about 4 in the last 8 months. Needless to say I bought about 20 new ones on the TP and new.
I have only made a couple fitteds to try and they were ok. I say, lay a dipe out and trace it if you like it. I think this is legal as long as you aren't trying to make money.
As far as screwing up, even as a beginning sewer, I don't think any of my stuff was unusable. You can always rip the stitch out ya know.
I do also think it is hard to know exactly what type of body your babe is going to have. That is why I went no further than newborn and small with my sewing.
Since you can make fitteds with no elastic, like mother ease, I would say that that prolly cuts down on the time. I found the elastic to take some time and was my least favorite part.
I say, if you have the time, it is a wonderful way to prepare for the new babe and have a fun (and sometimes frusterating) thing to do.
There is a place that will make you fitteds out of any fabric you have, this is what I did with my leftover hemp and flannel. It was 5$ a dipe and I even sent in some clothes that I got at the free box.link here
I had 5 larges and 2 newborns made just because there wasn't enough fabric for bigger and this way my DD could have play dipes. You do have to pay shipping both ways, although on her end I think it is less than actual.
I do have to say that the NBs looked really small to me. I either can't remember DS being that small or they were just super small. The Larges seem to be a true larges.
Hope that helps.
Oh, and also, I think once you find a pattern you like, you can spend one day cutting all the layers and another day sewing them up. This makes things go a bit faster because you are doing the same thing over and over.
