Q: "How can I create a draft Page Layout?"

A: I use Excel spreadsheets like this to mock up Page Layouts quickly. Note in the spreadsheet that I put codes (listed below) to designate field types. I encourage you to customize it for your own purposes--and let me know what you come up with!

A	Address
C	Checkbox
$	Currency
D	Date
E	Email
F	Formula
L	Lookup
M	Multi-Picklist
#	Phone
P	Picklist
S	System
T	Text
