Problem: Article: In theory, you can harvest rubber from a tree that is younger and/or smaller than these recommendations. However, the amount of latex you'll harvest is very unlikely to be worth your time and effort. Also, since younger trees can be more tender and have thinner bark, you're more likely to cut through into the cambium—the very thin layer between the bark and wood that's responsible for the tree's growth. Doing so is bad for the tree's health. Face the tree, and plan a cut that will descend from your left to your right, no more than halfway around the tree. The cut should descend at a 30-degree downward angle from left to right, since the latex-containing lactiferous vessels descend at a slight angle from your right to left.  Use a level, a protractor, and a piece of chalk to mark out your cut, if you want to ensure greater precision. The planned cut can be made at any height. Use an awl (a sharp, pointed tool) to cut along the line you made, just barely breaking through the surface of the bark. Other sharp-ended implements will work as well, but may offer you less depth control.  If you cut more than 6 mm (0.24 in) deep, you'll pierce the cambium and damage the tree. You'll know you've pierced the cambium if the latex doesn't flow well and the area turns dark brown. If so, leave the tree alone to heal (for several months, at least) before tapping it again in another area. The latex will flow down the channel you've just made, so you need to place a collection vessel at the bottom right end of the cut. Traditionally, metal collection buckets are tied securely to the tree with sturdy rope.  The bucket will be fairly heavy when it's filled with latex. So, if you're concerned that you may not be able to tie it securely enough to the tree, consider supporting the bucket from beneath with scraps of wood, other buckets, concrete blocks, etc. Alternatively, you can plan out your cut so that your collection bucket will rest on the ground. But you should still tie it snug up against the tree bark. Latex will flow for about 6 hours from a fresh cut until it coagulates, so check back after that amount of time to see how much you've collected. If you're lucky, the 4 L (1.1 US gal) bucket may be more than half full! For the best results, you should make your cuts early in the morning and collect your bucket around mid-day or early afternoon. You can, for instance, make a cut at the same height on the opposite side of the tree on the second day, then make a new cut on the original side (but either higher or lower on the trunk) on the third day. Over time, the original cut will heal over and you can create a new cut there.  If the latex production reduces noticeably, give the tree several days of rest before tapping it again. Creating new cuts each time you collect won't produce the same quantity as an alternative method—creating a single channel that you'll use to collect on a set schedule over a long period. However, the daily cut method is easier to do and can still produce ample latex.
Summary: Tap a tree that is at least 6 years old and 50 cm (20 in) in circumference. Visualize your cut, 30 degrees downward from left to right. Make your cut 4.5 mm (0.18 in) into the bark. Attach a 4 L (1.1 US gal) bucket to the tree. Retrieve the bucket of latex 6 hours later. Repeat the process with a fresh cut each day.

Problem: Article: Whether you're making a physical or digital memory book, the first thing you need to do is decide what you want your book to be about. Common memory book themes include:   Family members – Make a book about a specific loved one. In addition to photographs, you can also include things he or she wrote (like letters and postcards), drew (like pictures your child has made), or anything else that is flat enough to fit inside a book or to be scanned into a computer. You can also include documents associated with this person, such as a report card, a copy of a birth certificate or marriage license, or a birthday card he or she received. If your child is young, you can start a memory book now and add to it as he or she grows up.  Events – Weddings, birthdays, bar/bat mitzvahs, quinceañeras, graduations, and anniversaries are all popular choices when making a memory book. Holidays, like Christmas or Valentine's Day, are also common themes. If the event or special day happens annually, you can add a new page or chapter each year.  Vacations – Use your memory book to relive a fun vacation or share it with others. This is an especially good idea if you went to an exotic location and took a lot of pictures. You can also include things like your plane ticket stubs or even a pressed flower you brought home with you. If this is an annual family vacation, consider adding a new chapter each year. You can put every chapter in the same book or a different one per year.  More specific combinations – This option is especially popular for parents making a book of their child or children. They can be about one specific event, such as "Duane & Derrick's First Halloween," or one that covers a longer period of time, such as "Melissa's First Year of School" or "Becky's Birthdays from Six Through Ten." There aren't many rules for what you can include in a memory book. Just make sure whatever you add fits your chosen theme and, if you're making a physical memory book, make sure that all of your items are relatively flat and can be attached to the pages with ease.  Physical memory books often include photographs, illustrations, poetry, quotations, ticket stubs, greeting cards, programs, postcards, stickers, and even small mementos like coins or tokens. Each item is often paired with a written explanation for its context. In addition to photographs and other scannable documents, digital memory books can also feature sound and video. Remember that a memory book is different from a general photo album. Don't include every related photo you've shot. Instead, choose only a handful that tell a story. Many memory books are made through collaboration. Consider asking other people to help make your memory book. They can help by either making a particular page or chapter or by simply submitting photos and other items they may have.
