https://fabrics-store.com/ All different kinds and weights of linen.

I use the package of kitchen towels from Michaels crafts. The package makes it look like there are patterns on the fabric, but there aren't.

In the same area are some wax pencils that are very helpful for transferring patterns.

I don't have this app on my phone or I would share some of my embroidery.

I'm pretty much self taught, but have been doing it since I was a teen!

I really hope your daughter enjoys hand embroidery!
