One way to keep your hand cut,45 deg, bias tapes neat and uniform
is to lay them up on clear poly (Home Depot plastic sheeting) SNIP
Peel the backing off , finish and inspect.

While the tape may be more convenient, the extra thickness of the edge
sticks out. What I like to do is roll out a piece of plastic wrap,
roll a piece of peel ply on top, paint on a little resin, roll out the
bias tape, saturate with resin, roll out the narrower hemmed tape,
apply a light coat of resin in the corners, apply the whole works.Snip

It depends on the surface, but if I can lay the tape on top: I use a
cloth marking pen (marks disappear in an hour or so) to mark the cloth
on the cutting table, roll the tap up, mark the surface on which the
lay-up will be done for the proper width, wet the surface with a
light coat of resin, lay the tape out as I unroll it (push to widen,
or pull the narrow - do the same while stippling) then using a one
inch paint brush, stipple the resin into the tape.

While each of these systems works,most stippled corner tapes that I
have seen come in heavier than they need to be. Ed's method of
placing a slightly narrower tape under the final tape gives a thinner
edge, and is what I do, but the peel ply can hide inspection and
makes the joint smother but also heavier. Most scratch built composite

airframes that do not pay close attention to these small weight
increases
ending up weighing more than necessary.
That straight tape edge adds points at Oshkosh and less weight allows
one to climb faster. Reggie

Ok, I want to reinforce all my corners with fiberglass tape. Aircraft
Spruce sells a 50 yard 8.7 oz tape to do this job. Can anyone tell me
why I shouldn't use cut strips of my 1.4 oz cloth instead of this very
heavy tape?

If you use enough plys so that the strength exceeds the peel strength
of the joint and is as strong as the skins you are joining ,go for it.
It may take a few layers and will use more epoxy.
