I see why you don't want to seal up all the holes, but it would be better to make vents that you can open and close for temp. control
and fill the gaps for insect and cold control
You can buy styrofoam inserts that fit the corregation shape of the poly sheets
Or you can use gap fill spray foam, its comes in a spray can, and fills large gaps with insulation foam that hardens, around windows and things, you can get some at Home Depot

Craig,
Well I didn't want to fill them permanently, but I did do a fair job temporarily sealing them for this fall.
I used that expanding foam to seal the peak. This is now permanently sealed. I have some of the foam strips, but they are designed to go on top of the sheets. I need them to go underneath the sheets for the eaves so these dip where they need to bump and vice versa.
Another reason I didn't want to do anything more permanent on the sides is because I plan on replacing the plastic sheeting some day with the corrugated poly. When I can cover it with that ($$$ permitting), it will be more sensible to seal the gaps and install the vents.
