I intended to use terry squares for my eldest 11 years ago,as there wasn't much choice and that wa the only option at the time.I used them once,found them too much hassle and used disposables.I tried again with my number two baby and we used them till she was trained.With my other babies I used disposables simply cos terries,pins and the old fashioned plastic pants that had a tendency to split hen you least wanted it were too much work.
With number 7 I have recently switched to Kushies,which we're happy with.Although they make all in one nappies we use the originals and the separate wraps .It's almost as easy as disposables at change time,so much easier than the old terries I'd used.I have 15 nappies and four wraps,which gives us enough to keep my little one in nappies and a full load for washing every couple of days.
.I still have 2 dozen terries for mopper uppers of any kind,towels,changing mat,cleaning,under the potty,and as a pad in the highchair,car seat and pushchair.Many,many uses,like Youngmummy says,they dry quick.They also boil wash if you've anything unpleasant needs clearing up.
I'm also a big fan of Cheeky Wipes,reusable wipes,well worth a try too.
