Draw/write with them a lot. Trying to draw every day. After having known about Inktober from the beginning, I never actually followed the prompts until the 2024 ones. Decided to catch up on all the old prompts under <a href=\"https://mastodon.world/tags/PastInktober\" class=\"mention hashtag\" rel=\"tag\">#<span>PastInktober</span></a>. Due to changing servers a lot of the earlier ones have disappeared. I draw with fountain pen. If I really mess up, I fix it with collage.<br />If I notice you use Ai images I will block you.</p>", "url": "https://mastodon.world/@Parker51", "manuallyApprovesFollowers": false, "discoverable": false, "indexable": false, "published": "2025-02-28T00:00:00Z", "memorial": false, "alsoKnownAs": [ "https://penfount.social/users/FPLover" ], "publicKey": { "id": "https://mastodon.world/users/Parker51#main-key", "owner": "https://mastodon.world/users/Parker51", "publicKeyPem": "-----BEGIN PUBLIC KEY-----\nMIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAyMU/OwZkgBMpIyO36zo8\nN0XwtKvve+hsuJxLOveCDQJvmtYlDNVbnYVWFUloqsQjiorWhnVQiz/CnBMxWtmI\nGu4KuEo0BVGJU4uzQCpu4nVvAz4GnKBT9cBTCcfFW7Cn7FeXo40KV+gwnmFzXfW7\niopNjYrfod1E7nAOqS8pF/d/5j400Eg/CLwlhs4LaEC4p93ClN4/Kte6+IAEuBDI\nRQGn+faCmRktPK6pHwiYT8gnBnCbQ7qEdV+mKApYH9+RwaN9sZe47k0xHYO3EPge\nr9e9N0tek6IkBGesLTl7q4NbmaLl7NxHVz0EYqaUdiCa9601DuZEUaVNbg252aOh\nlwIDAQAB\n-----END PUBLIC KEY-----\n" }, "tag": [ { "type": "Hashtag", "href": "https://mastodon.world/tags/fountainpens", "name": "#fountainpens" }, { "type": "Hashtag", "href": "https://mastodon.world/tags/pastinktober", "name": "#pastinktober" } ], "attachment": [], "endpoints": { "sharedInbox": "https://mastodon.world/inbox" }, "icon": { "type": "Image", "mediaType": "image/jpeg", "url": "https://s3.eu-central-2.wasabisys.com/mastodonworld/accounts/avatars/114/080/893/028/845/869/original/ad233b359f101a5a.jpg" }, "image": { "type": "Image", "mediaType": "image/jpeg", "url": "https://s3.eu-central-2.wasabisys.com/mastodonworld/accounts/headers/114/080/893/028/845/869/original/d5db40fd21f9ec26.jpeg" } }
