Oh sorry, didn't check myself to be sure.
Changing the type on the pandas side should work, like so:
```python
import pyarrow as pa
import pandas as pd
df = pd.DataFrame(({
'a': ['a', 'a', 'a', 'b', 'b', 'b', 'c'],
'b': [1, 2, None, 4, 5, 1, 0],
'c': [1.5, 2.0, 3.5, 5.0, 8.0, 10.0, 'a string'],
}))
df['c'] = df['c'].astype('str')
pa.Table.from_pandas(df)
# pyarrow.Table
# a: string
# b: double
# c: string
# ----
# a: [["a","a","a","b","b","b","c"]]
# b: [[1,2,null,4,5,1,0]]
# c: [["1.5","2.0","3.5","5.0","8.0","10.0","a string"]]
df.to_feather('file')
pd.read_feather('file')
# a b c
# 0 a 1.0 1.5
# 1 a 2.0 2.0
# 2 a NaN 3.5
# 3 b 4.0 5.0
# 4 b 5.0 8.0
# 5 b 1.0 10.0
# 6 c 0.0 a string
```
