Formatting script output into columns

[pfildes]

In my script I have created a list of subdirectories. How can I present this list formatted in to four columns?

i.e.
Folder1 Folder2 Folder3 Folder4
Folder5 Folder6 Folder7 Folder8

So far I have the following;

for tmpDIR1 in `ls -l /opt/myapp | grep '^d' |awk '{print $9}'`; do
	if [ -d "/opt/myapp/$tmpDIR1/app" ]; then
		echo $tmpDIR1
	fi
done

pipe to paste command perhaps?
