Lemme say this again, piecing is HARD!!! Even if you're committed you will still probably want to walk away... She has to be committed, not guilted into it.
If you wanna see how hard piecing is, read BluWave's stitch, she only started her thread a year after starting to piece and she still struggles, but her H is committed so together they work hard to try and get through it.
