Molly Weasley found the situation horribly embarrassing. She considered herself a simple witch; there wasn't anything special about her.
She behaved as any other self-respecting mother would. A mother lion protects her cubs.
She felt she had failed Fred.
She did not fail Ginny.
Molly couldn't help the surprise at discovering they wanted to give her a Chocolate Frog card for that, but who was she to argue?
In addition to casting the curse to end Bellatrix LeStrange, the makers needed something else to fill in her biography. A questionnaire arrived asking about her hobbies, her likes and dislikes, and if she wanted to share anything else that the public may find interesting.
She noted her love of baking and knitting. She wanted to honor her twin brothers, Fabian and Gideon, whom she felt were more deserving of a card than her, having taken down five Death Eaters in an ambush before their early demise during the first war.
They put all of it on her card, even embellishing a bit, letting people believe she invented several household charms. That simply was not true! Everything she used had been passed down to her from her mother and her mother's mother before her.
She tried to teach many of them to Fleur, in an attempt to make sure they were passed to Bill's children. The French witch made it perfectly clear the spells she learned from her own mother were just fine. Ginny had learned many of them as a child, but she and Harry owned a house elf. Molly worried what would become of Lily. Hermione seemed interested in learning them for a time. The poor dear didn't have a mother to teach them to her, after all, and Molly found happiness filling that role. Belatedly, Molly realized Hermione's interest was much more academic in nature.
When the box arrived at The Burrow with her complimentary first run of cards inside, Molly invited the entire extended family over for dinner and a little package opening ceremony.
The teasing commenced immediately.
"I must have inherited my 'penchant for inventing' from you, mum," George said as he read the card.
Bill walked to the living room, grabbed an old family photo album, and opened it up to a picture of Molly pregnant with him, knitting needles visibly making baby booties in the background.
"You must have been a child prodigy to have devised such a complex spell at the age of 19," he noted with a wink.
Ron whinged, "You forced me to spend part of my childhood using a second-hand, spellotaped wand when you were secretly a Charms Master."
Charlie smirked at Ron, "They were hoping to build character in you, but look how that worked out."
Ron's ears turned red. "Say something about my character again. Go ahead, I dare you. This wand is excellent at making people eat slugs."
As the conversation devolved around her, Molly tuned out the argument starting at her kitchen table, glaring at the card, wishing she had said no when she was asked to be on it.
