Food preservation, trying vacuum sealing potatoes

In an attempt to figure out different ways to preserve my huge potato harvest, I've decided to try the vacuum sealer.

For this technique I washed the potatoes

Dried the potatoes , leaving them to dry for several hours.

Made the bag and packed the potatoes

Then sealed them.

I also tried slicing them and sealing like that.

This is my first time trying vacuum sealing potatoes so I will see how they do and report back later.
