Using a Serenity Loom?

There are oodles of YouTube instructions so check them out and if there is something you do not understand go to another site and see if the instruction are clearer.
Sometimes one speaker is better than another and says things that are easier to understand.
Check out this link and look on the right side at all the other YouTubers trying to help you master this thing.

Patterns:
You may want to think about purchasing a pattern/kit for your first project just so you know how it will look and you'll have all necessary pieces in one place.

Michael's and other full craft stores hopefully will still carry these or you may have to look online for a kit.
Enjoy - Good luck with making something neat for your new grandson...

Casting:
1. Make a loop using your yarn - a slip knot for crochet.
2. Slide the knot onto one peg on your loom and mark this peg. If your loom has an anchor peg, place it on a peg that's closest to the anchor.
3. Using your right hand pull the working yarn towards the center of the loom and then wrap the yarn counter-clockwise around the peg that's next to it going in a clockwise motion.

4. Keep wrapping the yarn around each peg until you've gone around the loom. Work clockwise if it's more comfortable for you.
The lines of yarn should be closest to the inside of the loom.
If your pattern calls for making knit stitches first, wrap another row of yarn around each peg so you have 2 levels of yarn on the pegs.
If you prefer to knit counter-clockwise around the loom, wrap the yarn around each peg in a clockwise motion.

Knit Stitch:
1. Take a loom hook and insert the tip under the bottom loop of a peg.
You can wrap working yarn around the anchor peg to secure it while you knit.
2. Bring the loom hook up and over the top of the peg. This will bring the bottom loop over the top loop on the same peg. Now you can take away the loom hook.
Avoid pulling the stitches too tightly because then it will be difficult to bring the bottom loops over the top loops.
3. Continue to knit each peg on your loom according to the pattern. If your pattern calls for some knit stitches and some purl stitches, follow its instructions. To make the garter stitch, knit every row.

4. Once you've knit the first row on your loom, use your fingers to push the knit stitches down towards the base of the loom. If you're making a row of knit stitches, wrap the yarn around each peg as you did when you cast on the foundation row and work the stitches. If you'll be making purl stitches, you don't need to wrap another row.
Keep track of how many rows you've made.

Purl Stitch:
1. You don't need to wrap another row around the pegs. Instead, bring the working yarn in front of the loom away from the center. Hold the yarn below the loop on the peg you're ready to work.
You'll need the working yarn below the loop so you can pull it up and through the loop.
2. Point the tip of the loom hook down and behind the loop on your peg. Push the loom hook through the stitch so the loop catches on the hook.

3. Turn the working hook so the tip points up and hooks onto the working yarn that's below the loop. Pull the working yarn up so it makes a loop.
4. Keep the loop on the end of your loom hook and pull it up so any of the stitches on the peg are lifted off. Then take the loop you just made and push it onto the peg. It should now be the only loop on the peg and you can bring the working yarn down below the next peg to make another purl stitch.
You can use your fingers to lift the stitches off of the peg before you place the purl stitch loop onto it.

Binding Off:
1. Cut the working yarn and leave a long enough tail to sew the end shut - about 2 feet.
2. Thread the yarn onto a tapestry needle or flexible plastic needle.
3. Place tapestry needle under the loop on a peg. The tip of the needle should be pointed up towards the top of the peg.

4. Keep pulling up on the yarn so all of it is worked through the loop on the peg. Once you've pulled it all through, use your fingers to lift the loop off of the peg.
5. Continue to bring the threaded needle through each loop and pull off each stitch. Work your way around the loom and bind off the loop from the final peg.
6. Hold onto the loop that's next to the working yarn and use your other hand to pull the working yarn. You should see the fabric begin to gather and tighten. Once you've pulled it as tightly as you'd like, insert the needle into the nearby loop and make a knot.
7. Cut the tail and weave in the ends.
