Kit Making - What format should I offer the instrutions?

I've been busy with a new round of kit making, filling in gaps where inventory has run low and putting together some new kits as well (some already available on my Etsy shop and some of which should go live within the next week or so).  As part of this, I've revisited the issue of the format of the included instructions.  Specifically - should I continue providing the instructions as printed pages, or should I move to a digital format - either as an included CD or as a digital download. 

As part of this process, I put together a Pro and Con list for each of the three format, trying to look at things from both my and my potential purchasers perspectives.  Here's what I came up with:

Paper Copies
Pros

• The kit is immediately complete, without need for further work on students part
• No need to have computer/internet access
• Hardest to reproduce - though not by much

Cons

• Weighs more - increases shipping rates, especially for international packages
• Bulky - especially in the case of my fish tutorial, which is 24 pages long
• Costs more - ink costs keep going up, and I have to pass those increases along in my kit prices. (I spend nearly as much on ink in a year as I do on beads).
• The instructions are printed on my inkjet printer, so if they get wet, the ink will likely run

CDs
Pros

• Instructions are part of the kit
• Purchasers can print multiple copies for their personal use if first copy is damaged
• Purchasers may also load the file onto their digital devices (tablets, iPads) if they like

Cons

• Many newer machines don’t have CD drives - could make it difficult for some purchasers
• CDs are fragile, and could be damaged/broken in shipping
• Ease of printing multiple copies makes it tempting to print extra copies for friends
• To make them look nice, I’d have to print CD labels - one more layer of complication

Digital Downloads
Pros

• I already offer a number of my tutorials as digital downloads - people seem comfortable with the format
• Purchasers will likely have the instructions well before their physical package arrives
• Purchasers can print multiple copies for their personal use if first copy is damaged
• Purchasers may also load the file onto their digital devices (tablets, iPads) if they like
• Purchasers may access the download from anywhere with an internet connection
• No printing or CD costs
• More and more people are comfortable with digital formats

Cons

• Instructions not an immediate part of the kit - Purchasers must take an extra action to access instructions
• Students must have an Internet connection to download instructions (but if they purchased my kit through Etsy, then they obviously do)
• Ease of printing multiple copies makes it tempting to print extra copies for friends
• Etsy doesn't have a built-in system for dealing with digital content as part of a physical sale, so I will have to email the download code to the purchaser, instead of allowing Etsy to provide it.

There are definite pros and cons for each format.  After way too much thought, I've decided I'm leaning toward digital downloads.  I think it's a clean, streamlined approach.  Personally, I like having my tutorials on my iPad - it's far more convenient for me than having to keep track of lots of pieces of paper, especially when I'm working out in my garden and there's a breeze.  For the download, I will email the Purchaser within 24 hours (48 hours over weekends) with the download code and will also include download instructions inside the kit itself.

But, I'm moving slowly.  So, through the end of the year if you purchase one of my older kits for which I've already printed instructions, you will receive a printed copy.  Unless it adversely affects shipping costs (such as in international packages) in which case I will send you a digital download code instead.  For newly minted kits, you will receive a download code for the instructions.  The instructions will be in PDF format. 

And, as a fail safe during this transition, if you have a preference as to which format your instructions come in - printed or digital download - let me know.  Send me a note with your purchase and I will make sure you receive whichever you prefer.

So that's where my thoughts are at present, but I'm curious if you have any preferences, one way or the other?  Let me know!  While I make the kits, I make them for people like you and your feedback helps me stay on track.
