I tried the beach towel clips but found them to be awkward and heavy.
This is what I turned to and I really like them.

They are the same as the smaller clips, but are about 2 1/4" and the grip on the fabric is stronger. I purchased the Clover brand (green) as I wanted to make sure they were good quality, though the linked ones above, may be the same quality.
Actually, it probably depends on how you want to apply the clips, as to what size you want to get. I also have used the 'bracelet' type, but once I used the jumbo wonder clips, I gave mine away.
