I started with backstitching on the upper half, which is mostly tree branches, also balloon string. There is more detailed backstitch on Winnie the Pooh, it requires several colors and some of the backstitch is over 1 thread. I opted to backstitch the balloon too, though it wasn't charted. Then, I moved onto the lower left quadrant which had hundreds of french knots. Maybe a thousand. All the flower bushes are adorned with copious french knots. Also, more branches and tree trunks were backstitched, and several colors of backstitch for Eyeore and Rabbit. Then I had to frog and redo one of the backstitch colors on Rabbit because it was too pale and indistinct.
Finally, I moved onto page 4 (lower right) and continued the cross stitch, finishing about 2 columns (1700 stitches). However, the full stitch count was 3,032 counting all the detail work on the previous pages.
I wonder if 5 days in April will be enough time to finish. What remains is about 1400 more stitches, 3 petit point sections, all the backstitch on page 4, and a considerable number of french knots.
