Mooin
Ich möchte gerne zum abschluss des Jahres 2025 diese Bilder da lassen. Ich kam zwar nicht viel zum zeichnen aber ein bisschen und fast passend zu jedem Monat💖
Nähen konnte ich tatsächlich mehr, darum habe ich etwas geschummelt😁
Ich wünsche euch einen Guten Rutsch ins neue Jahr💖💖💖

A little behind the scenes of crafting the winter cards for the stream this year! 💙❄️

A lot of cutting, gluing, finally drawing and then writing, printing and cutting extras, packaging everything, labeling into sending each card out!!
A lot of work but I’m very proud of how the cards turned out 💖

Merry Christmas @kirafairy.bsky.social 💙💛💚

A colourful coloured pencil art anime-style illustration of three girls enjoying pancakes together in front of a green hue background, indicating it’s Christmas. On the left, a cheerful girl with short white hair, blue eyes and small-ish blue wings on her head smiles while holding glowing string lights, which she is wrapping around the horns of another character to the right. On said right, a girl with light brown mullet-styled hair in braids and round gold rimmed glasses looks surprised, mouth open, in anticipation of pancakes a third character is holding. Said third character is in the centre, a blonde elf-like girl with long hair and pointed ears, who grins confidently, while holding a plate of stacked glittery pancakes in both of her hands.

Instead of following an #inktober prompt list I want to draw my girl in 31 different outfits and do my "own" inktober challenge. Some kind of fashiontober or... tiwitober :3

Hope you will like it!
