I wish you luck wiht your week of signing.
At first it becomes hard, yes and this is where you need to do hand exercises so you don't develop carpal tunnel.
Your hands and fingers are VERY important to you. Make sure you take good care of them. Moisturize them, if you can do this... take a cooking course offered by the DB community.
I know I had to relearn how to chop food because I kept chopping at my fingers & cutting at the tips of my fingers and it was painful. I would burn myself reaching into the stove.
CNIB taught me how to chop food, how to put the sharp knives away safely until it was time to be washed, handle hot dishes and I kick hubby out of the kitchen so I feel comfortable. Well.. too many chefs spoil the soup! HA HA!
As for print on palm..
This website provides in detailed format and it does rely on both you and your wife to train together.

The insensitive "Yoo hoo.. remma me??!?!" waving game in our faces is just stupid, period.
Just what happened to the same person they were before we lost our vision? Losing our vision isn't a license for some people to act like a complete doofus in front of us.
Aleser is correct that Print on Palm is much easier than Tadoma.
I grew up being exposed to all kinds of communication systems and this was like Sim-Com/TC, Cued Speech, Bi-Bi, ASL, SEE all because my parents thought it was best to expose my sisters and I to everything possible.
For example with one-hand ASL in palm, how do you differentiate P and K? G and Q?
So far for my wife and me, the BSL alphabet modified for the Deafblind is the easiest for her to sign and me to receive. So right now are both learning the DB BSL Manual Alphabet.
Demonstrate for the other signer to drag the letter in the direction it usually points when facing 'you'.
so they would put the 'k' in your hand then move slightly sideways (I said sideways because I can only do manual left handed)
If they 'p' (pee) in your hand wipe it on them. - no actually they would move it towards your pinky or 'down' (some will move it farther into your hand others will assume the pinky is the 'down'.
'g' would be just like 'p' across your hand', 'q' well you could wait for a 'u' but it would be moved 'down' like 'p' was.
'j' and 'z' drawn on the whole palm- then 'shown', 'x' is shown first then moved like the 'x' does.
Of course this was signing manual to blind friends that wanted me to show then another way to communicate- most of them have... 5-6 languages I have 1 and '2 halves' (half in Spanish, half in SEE)
This worked well for the 4 of us, but trying to have a conversation in manual is hard as poor a speller as I am. (We played 'telephone' )
I also learned to keep my other hand under there w/o holding on, just under so they could feel the tension in my non-signing hand if I was about to 'drop' a 'down' letter -- or when I needed to 'erase' letters-- which is often.
(erase) Instead of the 'normal' erase I'd use my hand like a knife edge (full palm kept being read as 'b') and 'sweep away' the letters already signed.
This was all improvise tho-
