Yes, it is possible to stretch a canvas on an already stretched canvas frame. This process is known as re-stretching and involves removing the existing canvas from the frame and replacing it with a new canvas. It is a common practice for artists who want to reuse a frame for a new artwork or for conservators who need to replace a damaged canvas. However, it is important to ensure that the frame is in good condition and suitable for re-stretching before attempting this process. **

It is generally not necessary to tighten a pre-stretched canvas, as it should already be stretched and primed for painting. However, if you notice any sagging or slackness in the canvas, you can use canvas keys (small wooden wedges) to tighten the canvas by inserting them into the corners of the frame and tapping them gently with a hammer. This can help to adjust the tension of the canvas and remove any slackness. Just be careful not to over-tighten the canvas, as this can cause it to warp or crack. **

Yes, it is possible to not erase a pencil on a stretched canvas by using light, gentle strokes when sketching out the initial drawing. This will minimize the visibility of the pencil marks and make it easier to cover them with paint. Additionally, using a kneaded eraser or a soft brush to gently lift off any excess graphite can help to reduce the visibility of the pencil marks without completely erasing them. Finally, using a light-colored ground or underpainting can also help to minimize the appearance of pencil marks on the canvas. **

Dark oak trees do not naturally grow in Minecraft because they are not part of the default world generation. Instead, players must find and collect dark oak saplings from naturally generated dark oak trees in roofed forest biomes, and then manually plant and grow them in a suitable location. This adds an extra level of challenge and rarity to obtaining dark oak wood, making it a valuable and sought-after resource in the game. Additionally, this mechanic encourages players to explore different biomes and adds variety to the types of trees that can be found and grown in the game. **
