Align Tape for Straight Line

tape tight and not really tight but kind of taut and that way I can move it back and forth and line it up exactly where I want I like my tape about a 16th of an inch onto the baseboards that way if you step away from the wall your line looks straight if it's even crooked a little bit on the baseboard if you're onto the wall and it's slightly crooked and you step back you'll be able to see that really easily so keep it a 16 inch on the baseboard bring it out stretch it
