Modifications:

For tube around headband - 40 rows not enough to meet in the middle. Increasing by 1 more stitch and then crocheting 8 more rows.

I widened the tail width by 1 extra row.

There aren’t instructions to do so, but I did a SC edging around the bows to join them together.

Overall Thoughts:
The design is SUPER cute as a photo prop, but not very practical for wearing in the park. It was very floppy and didn’t stand up well, especially in the 90 degree F heat at Disney World. It was perfect for my needs (just wearing it when meeting Pooh and getting some pics in Epcot UK near the Pooh and Eeyore topiaries) but I think if you want to wear it for a significant amount of time, you should either add cardboard inside or the ears and/or add wire around the ears/bow and into the headband to give it some structure <3 <3
