Hello, my informed friends. I have a quandary.
I am trying to write some letters in a format around A5 so I don't have to fold the sheet.
I bought the Tomoe paper sheets, but as much as they take ink well, they feel like toilet paper, and I would never send them to anyone.

What is a good paper/envelope, cream colored paper solution?
The requirements are:
• Cream colored
• I will write only one side (so show through is not a problem)
• Around A5, if I can find a backed envelope to fit the sheets
• Substantial weight (the 56gr of the Tomoe just won't do)
• Available in the USA without too much hassle or wait longer than a week

Any help is appreciated.
Grazie!
