1 pound of 222 gram strength granulated hide glue, regular clarity.

Let’s discuss gram strength: gram strength does not necessarily refer to the strength of the bond but rather the test used to determine the set time of the glue. A 192 strength glue will have a longer open time than a 251 - the lower the number, the longer the open time (and vice versa). So, if you are using hide glue for woodworking and need a little extra working time (say for guitar or violin work) many folks prefer 192. For gluing felt where a quick set is preferred, we’ll use a 251 (or higher, depending on desired set time - I’ve gone as high as 379).

Regular versus high clarity: if using in an application where minimal visibility of glue joints is desired (cabinet, carcase, guitar/violin or other musical instrument bodies) we recommend high clarity as it has less visible glue lines. For applications where visibility isn’t an issue, regular clarity is fine.

Multiple grams strengths in regular and high clarity are available in my eBay store.

I've used hide glue for many, many years for all types of piano, player piano and cabinet repair.  Gluing felt to wood, wood to wood (for joints like jack flange to wippen that may need separating years later) rubber pneumatic cloth to pneumatics, gaskets to various player parts, etc. etc.  Great glue, sets quickly.  Use with a glue pot or double boiler setup at 140 degrees. DON'T use the small glue pots made for hot glue chips - they get too hot.  If you exceed 140-150 degrees Fahrenheit it alters the glueFor the initial overnight soak (I use a glass jar filled about halfway up and punch a hole the size of my glue brush in the lid that came with the jar and that allows me to keep it covered when not in use) I fill the jar up about halfway and add enough water to just cover the glue crystals.

As with the vast majority of my auctions, this item is in stock, ready to ship and goes out the same day if ordered by 2pm CST.

Why use hide glue? It's been used for hundreds of years, tacks up quickly, holds well and if you ever need to reverse it a little moisture and heat will separate parts with little or no damage - that pretty much doesn't happen with modern glues.  If you glue down some felt and for whatever reason need to change it later it can be removed using the aforementioned technique and the glue residue sanded or scraped away.  Modern glues usually do not scrape well or sand without gumming up.
