I've read a lot of articles on patching the cracks in our plaster walls so I
know the basic steps.
So far, I've cut out the cracks and filled them with drywall joint compound
mix from HD), and tried my hand at taping and applying another layer. This
relatively easy. But I now see that the real test will be in how well I can
apply another layer
and "feather" the edges.
I was wondering if anyone here can give me some tips on how to do a good job
feathering. I have a 4", 6", and 10" drywall knife, mud tray, etc.
The key is a few extra light coats is a better way to go than globbed on
heavy ones that aren't flush with the existing wall and may develop cracks.
Use the 6" for the next 'light' coat. Very lightly sand using 120 grit
drywall sandpaper when the coat is dry. Followed by the 10" knife w/
the same light sanding. Not a biggee if you get just a little heavy, or
end up with a ridge or goober here'n there because you can sand that out
easily. Some mud companies "Hamiltons" for instance, make different
types of compound for pros.. From hard (for taping) to soft for
finishing. For texturing I use the taping mud as it's harder when it
dries after application. But All-Purpose should be all you need.

All the previous tips are right on the mark. Let me add one more essential
item, namely low angle lighting. If you can light your working surface nearly
parallel (without the glare in your eyes, naturally) then all the little flaws
will be highlighted. If you do the job to minimize these flaws, the wall will
appear almost dead flat in normal room light. Makes an amazing difference and
the job goes way faster. Good luck.
You've got the right tools. Patch, dry, smooth, and repeat. Look at
your patchwork using a troublelight held against the wall to sand out
all the irregularities. Gradually move to a finer sandpaper and large
putty knife. Use a latex primer. Sanding does make a mess so use
drop cloths or plastic sheets to help with the cleanup.
Does someone want to say something about mud consistency? I've been
mixing it with a consistancy of peanut butter for the initial layers, but
if a little thinner would be better for finishing layers.
