My first thought too!

Pickle pillow cases.

Perfect.

I agree with the pickle apron (with a top part, not just from the waist)

Great ideas, I like all the suggestions about stuffs to help in her pickling / jarring process... Use some InsulBrite for the cooling mat, those jars are really hot when they come out of the steamer! :) She would more than likely love a "pickle pickling set"... I agree, gotta make an apron to match if you have enough yardage! Or at least pockets on an apron!

How about a cute tote bag for her to carry more pickles to you in?

Do a jar quilt, there used to be a lot of "bug" quilts made for kids that the blocks look like jars.

My mom made some casserole snuggies this year for Christmas, that would be cute. Four corners come in and tie together around the dish

Aprons, checker board game, jar foundation paper piece, pair with icream fabric for a babyshower gift. A large block pattern with different veggies & primary colors. I've seen a quilt hanging in a restaurant with veggies and bright colors, it was unusual and fun.

I love the "jar quilt wall hanging" idea. It could be really, really cute!
