Q: Once you let go of the mouse button, you will see the dotted rectangle appear over a portion of the image. This will remove all parts of the image that are outside of the rectangular selection.  You can resize the cropped area as you would any image. If you don’t want to save your changes, press ⌘ Cmd+Z to undo them. If you want to save the cropped area as a brand new file (and keep the entire image from which you cropped it), Click “File,” then “Save As,” then choose a new filename. To revert the image to a previous version after saving, click “File,” then “Revert To,” and select “Browse All Versions…” Now, choose an older version of the image.
A: Click the Edit icon (a square with a pencil) to enter Edit Mode. Click the dotted rectangle icon in the editing toolbar, then select “Rectangular Selection”. Click and drag a part of the image you want to keep. Click Crop button. Press ⌘ Cmd+S to save your file.

Q: Allow the shells to dry for at least one full day and then rub oil on the shell.  Mineral oil not only restores the shine of the shell, but helps to preserve the shell. Similarly, you can use WD-40. However, when using this material, be sure to use gloves to handle the shells. You can use satin-finish polyurethane or coat with clear nail polish. This type of finish preserves the shell's organic look while giving it an extra glossy shine. Do one side of the shell each day. Allow the shell to dry completely before starting on the other side. Each side can take about a day to dry.
A: Rub mineral oil over each shell to give it a deep gleam. Spray the shells.

Q: You will need a double-sided (coarse and fine grit) synthetic sharpening stone. You will also need a honing steel, which is typically sold in the form of a lightly-grooved, magnetized iron rod. Both of these materials can be found at your local hardware store. Sharpening stones have two sides with different grits. The grit measures how rough the stone is, and thus how severely it sharpens. Higher numbers stand for finer grits meaning the lowest number is the roughest surface. This hand provides the control and keeps the edge down on the stone as you work.
A: Gather the necessary materials. Hold the knife with the handle in your dominant hand so that your index finger is on the edge of the blade, almost where it meets the stone.

Q: If you're just making a sample swatch, chain (ch) up 17 stitches. For a larger swatch or blanket, chain 34 or 51 stitches which are multiples of 17. Wrap the yarn around your hook and insert it into the fourth chain from your hook. Continue to yarn over and pull through the loops on your hook to make a double crochet stitch. Make 1 double crochet stitch in each of the 5 chain stitches across the foundation row. Then make 1 dc stitch, chain 2 stitches, and make 1 more dc into the next stitch. Keep working across the row by making 1 double crochet stitch into the chain stitches. Skip the next 2 chain stitches and double crochet 1 into each of the next 7 chain stitches. Then dc 1, chain 2, and dc 1 into the next chain stitch. Dc 1 into each of the next 7 chain stitches. Keep repeating this pattern until you reach the end of the row. Flip the work over so you can begin crocheting your first real row in the zig zag pattern. Make 3 chain stitches and skip the stitch closest to your hook. and dc 1 into the next 5 stitches. Decrease the number of stitches in this row by double crocheting 2 of them together. Then you'll need to double crochet 1 stitch into each of the following 5 stitches. Insert your hook into the next 2 chain space and make 1 double crochet stitch. Chain 2 into the same stitch and double crochet another 1 stitch into the same stitch. This will form the point of the zig zag. Make 1 dc stitch into each of the next 7 dc stitches. This will bring you across the other diagonal side of the zig zag. Then skip 2 double crochet stitches and dc 1 into the next 7 dc.  Remember to double crochet into each of the 7 stitches across the row. Insert your hook into the next dc stitch and make 1 double crochet stitch. Chain 2 into the same stitch and double crochet 1 more stitch into the same stitch. To work the zig zag pattern, keep repeating: Dc 1 into each of the next 7 dc stitches, skip the next 2 dc stitches, dc 1 into each of the next 7 dc stitches, and then dc 1, chain 2, and dc 1 into the next stitch. To finish the row, make 1 double crochet stitch into each of the next 5 dc stitches. Join together the next 2 stitches and dc 1. Turn the work to make another row, if desired.
A:
Make a foundation chain that's a multiple of 17. Insert your hook into the fourth chain and make 1 double crochet stitch (dc). Dc the next 5 ch stitches and dc 1, ch 2, and dc 1 into the next stitch. Dc into each of the next 7 chain stitches. Finish the foundation row by double crocheting and skipping stitches. Turn the work, chain 3, and skip the first stitch. Dc the next 2 stitches together (dc2tog) Insert your hook and dc 1, chain 2, and dc1. Dc into 7 stitches, skip 2 dc, and dc in the next 7 stitches. Dc 1, chain 2, and dc 1 to make another zig zag point. Continue to crochet in zig zag pattern until you reach the last 8 stitches. Dc 1 into the next 5 dc stitches and dc2tog the next 2 stitches.
