Cellophane bags are fantastic. I like to have the 4 oz, 8 oz, and 1 lb sizes around the house, just in case I need them. I like to package bath bombs, bath salts, and, as you can see from the picture to the left, little kits of things to give away. (Also great for cookies and chocolates!) I like to use cute twist ties (Daiso is awesome for this, or try your local chocolate making store) or ribbons as closures.
Note...I've tried "cellophane" bags from the dollar store, but they aren't cellophane...and they kill the scent!
I know you can use plastic sandwich bags for this task - but beware! Sandwich bags are made out of polyethylene plastic, and this can kill your fragrance and essential oils quickly. I learned this the hard way - 20 bags of bath salts for a class, and not a single one smelled like anything!
I love Daiso, the Japanese $2 store! If you have one near you, check out their selection of sushi and onigiri packaging. It's great for things like bath cupcakes or beeswax candles (especially ones that look like sushi)! It's inexpensive - 8 or 12 or 16 for $2! - and it looks pretty cool. Check out their twist ties, cellophane bags, and silicone molds. Their cookie and chocolate mold section is great for cute things!
For bath cupcakes, I like to re-use small cupcake containers (we get them for Games Night, so we always have some around the house). I realize it means I have to give someone 12 fizzing cupcakes, but is that a bad thing?
Whether you're making products for yourself or sharing it with loved ones, labelling is vital. It helps you remember the ingredients in your favourite body butter and it lets others know not only about potential allergens, but shows off the awesome ingredients you are using in your creations. You might remember what something is today, in six weeks you won't have a clue what's in that spray bottle in the cupboard (and when you start using mentholated foot lotion as facial moisturizer, you'll thank me for this reminder!).
When labelling bottles, clean them with rubbing alcohol prior to affixing the label. I had to fight with the kids at craft group to do this because the bottles may seem clean, but oils from your hands, minute dust particles, and little bits of surfactant can make the label come off, and that's irritating.
I like to spray my labels with acrylic sealer (find this in art stores or stores like Michael's) if they are going to be used in the bath. It'll keep them waterproof and affixed to the bottle. I do use an Epsom printer with water proof inks, so that keeps the writing itself water proofed, but it won't keep the label on the bottle!
On top of it all, it's fun to name your products and create adorable labels! My favourite product to label is "Cyclomaniac"...my anti-frizz spray. Yeah, I seem to be the only one who appreciates the name, but it makes me smile every time I use it.
