Oof, the shipping😬 personally I’d limit it to $5-10 for the shipping itself unless it was a need. However! I think your strawberry cow is so freaking adorable!! I think in total (shipping and all) the most I’d pay is about $35. Is that reasonable? I also wouldn’t want to short your work, so you might have better luck selling it for a better price at little venues/stands at fairs or festivals, you know? That way, you get all the money for yourself and there’s no shipping or fees to worry about
If I were selling it personally I would do $5 for supplies (unless the yarn cost more than that), $20-30 for time, $5 for skill from extra sewing effort, and $20 for shipping to be a total of $50-60 free shipping with you keeping ~$30. The yarn is pretty chunky giving you a lot of size without so much time and having that size justifies a higher price as well as your quality definitely seems great allowing you to justify being out of some people’s budget.
I do like the comment about increasing the price of the product to cover the cost of shipping. It’s an old trick to get reimbursed without it being described to the customer as a shipping charge, it actually makes it seem like you’re getting a deal as a customer. Like on Etsy a good rule of thumb is offering free shipping and then increasing your prices by about 20%
